Recent Events

i recently completed a long held vision and have now travelled every major interstate across the contiguous United States of America! My most current installment of travel led me across the extreme north of the USA from I-75 to I – 65 to I-94 to Interstate 2 to I-90 to Interstate 97 to I -5 From NC, through TN, KY, IN, IL, WI, MN, ND, MT, ID, WA, OR, ending in my birth state of CA.

i am eternally grateful for all the folks who made my trip possible. In particular thanking Michael Gentry, Rob Routhieaux and the Rainbow Walker. Couldn’t have done it without you! Giving thanks for all the support on this path really, it is sometimes only through grace and gifts that it may be.

Below are some samples of my botanical endeavors along the way. The main focus of this class to cover woody plants follows

Indiana

Indiana was a stopping point on my way to the North. My father graduated from Ball State University in Muncie. It was nice to visit a garden while holding him and others connected to Indiana dear. Minnetrista was the garden selected http://www.minnetrista.net/ and it resides in Muncie too. This compound is the old time home of the Ball Jar family. i have employed the use of hundreds of ball jars in my time. A visit for that reason alone seemed fitting. They have nice native gardens and a focus on sustainability. There is also an excellent museum and youth education facilities. Interesting gardens connect the homes of the Ball Jar brothers. The walkways and sitting places made me reflect on all the magic and drama that must have unfolded for so long there. The history of the Munsee tribe of Delaware Native Americans who lived there makes me reflect even more.

Minnesota

How many are familiar that Minnesota holds the headwaters of the mighty Mississippi River? The flora of this corridor is very similar to my home in Appalachia. Local parks (Minnehaha) in the Minneapolis/St Paul area and Munsinger/ClemensGardens www.munsingerclemens.com in St. Cloud were my new additions botanically for this trip. However, past visits have led me to the most excellent Arboretum www.arboretum.umn.edu and the Como Park Conservatory which are well worth visiting if ever in this area.

Munsinger excels as a pretty place garden on the water. Not many plants are labeled however. A couple of them stumped me including something that looked akin to Globe Amaranth (Gompherena sp.). See the photo album to reference what i am talking about. The layouts are grand and infrastructure elegant.

North Dakota

i once again picked up the trail of Lewis and  Clark in North Dakota. i camped at Cross Ranch State Park close to where they spent the winter before traversing the rockies to the coast. Plants of note included Germander (Teucrium sp.), Nettles (Urtica sp.) and a very fragrant Artemisia. Trees included huge Poplars (Populus sp.) on mesic sites, Ash (Fraxinus) and Box Elder (Acer negundo) were other major deciduous trees. The park has a downloadable PDF listing quite a few plants. The link follows.  http://www.parkrec.nd.gov/parks/crsp/nature.html

Native American heritage felt strongly present including the Mandan, Hidatsa and Arikara tribes. i visited a historic site where native American villages once stood along the knife river www.nps.gov/knri . Witnessing their mound homes with thick thermal mass was moving. i took note there of snowberry one of the plants known as buckbrush (Symphoricarpos sp.).

The Badlands of Theodore Roosevelt National Park were inspiring as badlands always are…Part of an ancient sea! Mostly grasslands before and after besides. Wheat (Triticum) and Corn (Zea maize) are the big grains. Fracking for natural gas has led to massive industrialization…

Montana

            Fracking and grain harvest continued into the big sky state. The typic granaries awe in their size. Amazing the truck traffic in such a remote locale! Giving thanks to the natives of the land including Kootenai, Blackfeet, Salish and all others.

 i finally made true a long held dream to visit Glacier National Park. Now one of my favorites National Parks ever! The park has so many flowers even in September! The namesake glaciers are vanishing and may be gone in the next 10-20 years! Many different eco types occur depending on elevation, aspect, soil type and water. i only spent a little time on the Eastern side where fruits were prevalent. My favorite part was a hike through the Alpine zone at Logan pass to the Hidden Lake overlook. Some plants of note there included Glacier Lily (Erythronium sp.), Monkey Flower (Mimulus lewisii?), Gentian (Gentiana sp.) Indian Paint Brush (Castilleja), and Wild Onions (Allium).  

Another hike to Avalanche Lake combined ancient Western Red Ceder (Thuja plicata) overstory with a Devil’s Club (Oplopanax horridus) understory. i am always excited to meet a new member of the Ginseng family (Araliacaceae) as was the case with the Devil’s club. Coming out of Glacier going south towards Missoula are numerous fruit orchards largely containing Cherries! Lots of Huckleberry products for sale as well… Yum…

Oregon

         Oregon is one of my all time favorite states and i feel thankful to have had more time there. Crater Lake National Park has been on my list of places to visit for at least 15 years. Yet another dream come true this trip for me. White bark Pine (Pinus albicaulus) Pondersosa Pine (Pinus ponderosa) and Douglas Fir (Pseudotsuga menziesii) are some major trees. i took a nice hike through old Mountain Hemlock (Tsuga mertensiana) forest to the beautiful Plaikni Waterfall. Notable plants included a flourescent pink monkey flower (Mimulus sp.), Prince’s Pine (Chimaphila sp.), mycotrophic Pinedrops (Pterospora andromedea), and the deadly poisonous Monk's hood (Aconitum sp.) On the way out i took note of copious amounts of Indian paint brush (Castilleja) and Red Elderberry (Sambucus racemosa). At a certain point on the way down from the lake a Ranunculaceae member maybe a type of Pasque flower (Anemone or Anemonella) stopped me in my tracks with its wind swept wispy beauty…

         Ashland Oregon has an incredible public botanical garden as part of a city park. It is called the North Mountain Park Nature Center http://parks.ashland.or.us/NorthMountainPark The garden focus is on various topics such as ethnobotany, native plants, butterfly/bird gardens, heirloom plant gardens and more. Blue Elderberry (Sambucus nigra ssp. cerulea), Hawthorn (Crataegus) and Himalayan Blackberry (Rubus armeniacus) were some fruits ripe for the picking. Ashland also contains an arboretum throughout the public Lithia Park which has some great specimens.

          The local Hot Spring hang out known as Jackson Well springs www.jacksonwellsprings.com has neat interest for plant people in addition to healing waters. Veggie gardens support the onsite café and medicinal plants are layed out according to healing systems of the body. They also have moon gardens around the intriguing Goddess Temple www.goddesstempleashland.com . Plums (Prunus sp.) were ripe for the picking too! Himalayan Blackberry is a prominent invasive that nonetheless has some of the best fruit for the genus that i have ever tasted! This town is a dream come true for the botanist, foodie, good life quality part of you.

California

            My ride into California flowed well leading me to walk around 25 miles along and out of the South Yuba River Basin. The walk was part of a pilgrimage in honor of Frank Cook and John Olmsted amongst others www.plantsandhealers.com . i took note of over 80 species of plants while we kept a fairly brisk pace of 8 miles a day.  Overstory members of note included Canyon Live Oak (Quercus chrysolepis) Ponderosa Pine (Pinus ponderosa), Douglas Fir (Pseudotsuga menzisii), Sugar Pine (Pinus lambertiana), and Incense Ceder (Calocedrus decurrens). Midstory trees and shrubs included Western Redbud (Cercis orbiculata), Black Fruited Dogwood (Cornus sessilis), Blackberry (Rubus), California Bay (Umbellularia californica), California Hazelnut (Corylus cornuta var californica) and several members from the Buckthorn Family (Rhamnaceae).

             After four days i was humbled to acknowledge physically that hiking on would not be good for me. Luckily we had convened a gathering of friends and supporters to share company and talk about plants. We crafted a mead on Sunday 9/18 in honor of the plants we had met and the birthday of our friend Lydiyah Sea. Turtle finished the hike yesterday and i met him at Lake Tahoe. It is hard to really comprehend him and others hiking the whole hundreds of miles from the Pacific ocean to the Sierra mountains or vice versa. Now at least i can relate a LITTLE bit from my 25 mile stint.

Monographs of Top Tree/Woody Plant Families Occurring around Appalachia and other temperate places

              The focus of the current class is woody plants. Much information comes from my graduate research on the plants of Appalachia like many of the classes this year. However, it has since been expanded to cover information about woody plants from other temperate areas as well. Here are featured 22 of the approximately one hundred and sixty plant families occurring in the Blue Ridge part of Appalachia (Wofford, 1989). The focus is on families that include a majority of woody species. Families are included here in monographs because they have members representing a multitude of uses across a broad spectrum of topics. All families are listed alphabetically by botanical name. A common name corresponding to the typic genus for the family accompanies the title. In the case of the Aquifoliaceae and Caprifoliaceae there is no corresponding typic genus known and another common name has been chosen.

               Due to time constraints some notable families that are useful or make up a sizable part of the Appalachian woody flora have been excluded. These include Witchhazel (Hamamelidaceae), Mulberry (Moraceae), Olive (Oleaceae), and Elm (Ulmaceae). The references consulted for the statistics of family geographic representation include Flowering Plant Families of the World (Heywood, Brummitt, Culham, & Seberg, 2007), Guide to the Vascular Plants of the Blue Ridge (Wofford, 1989)  and a Synonynized Checklist of the Vascular Flora of the United States, Canada and Greenland (Kartesz, 1994). The work by the Karteszs also covers Puerto Rico, Hawaii and the Virgin islands. Heywood et al. split some families up that are considered as larger in the older sources of Wofford and Kartesz. Notations are included in the discussion of taxonomy for individual families. Several other books might be worth referencing for those interested in plant family patterns. (Castner, 2004; Elpel, 2004; Judd, Campbell, Kellog, Stevens, & Donahue, 2008; Raven, Evert, & Eichhorn, 2004; Spears, 2006; Zomlefer, 1994)

The role of trees is something important to consider. Pragmatically trees provide habitat, food, building materials, textiles, shade, paper, carbon sequestration and many more services as well. However, even energetically certain trees have given me more solace than any person ever could. Many intangible roles trees have played in society.

Conifers vs Hardwoods

              One of the biggest distinctions in the tree world is between hardwoods also known as broadleaves and confiers. Conifers are a more ancient lineage with a once wider distribution. The two main families of conifers include the Pinaceae and Cupressaceae. Pinaceae members tend to have needles in different numbers and arrays in place of broad leaves. Pines (Pinus), Fir (Abies), Spruce (Picea), Douglas Fir (Pseudotsuga), Hemlock (Tsuga), Classic Cedar (Cedrus) and Larch (Larix) are all included in this family.

            Cupressaceae members often have foliage with imbricate (layered) scales that are sharp to the touch. The most common member is Juniper (Juniperus). Cypress (Cupressus) is another major one. Many trees that formerly went by Cupressus in the Americas have changed to the genus (Callitropsis) (Judd et al., 2008).  Thuja and Chamaecyparis occur in the east and the west and go by a host of names including types of Cedar. Incense Cedar (Calocedrus) is a common genus in the western United States.

             The formerly separate members of Taxodiaceae are now included within the Cupressaceae family (Judd et al., 2008). North American members include California Redwood (Sequoia sempervirens) Giant Sequoia (Sequoiadendron giganteum) and Bald Cypress (Taxodium spp.). Dawn Redwood (Metasequoia glyptostroboides) was a species thought to be extinct until it was found in the 1940s’ (Judd et al., 2008). This sub-family holds the tallest and biggest tree titles for the planet and also some of the oldest trees as well.

              Smaller families of Confiers include the Yew (Taxaceae), Podocarp (Podocarpaceae), Monkey Puzzle (Araucariaceae) and Umbrella Pine (Sciadopitayaceae). The Podocarp and Monkey Puzzle families often occur in the Southern Hemisphere. One of the largest trees i have ever encountered was a Podocarpus centuries old growing near 10,000 ft and the Cerro de la Muerte in Costa Rica at the Seeyle family land www.lasvueltas.com. One of my greatest memories from travels with Frank Cook.

              In the northern temperate regions conifers tend to grow on more harsh sites. Some examples include dry, fire prone, wind swept, snow buried or frigidly cold. They tend to have more shallow roots, thicker bark and quicker growth as some adaptations for their chosen path. Most of them will not sprout from stumps. More conifers are put into plantations than probably any other trees. Pines in particular are popular in this regard. Confiers are sometimes also called evergreens though a number of members are deciduous including Bald Cypress, Dawn Redwood and Larch. The Hemlock Wooly Adelgid and Balsam Wooly adelgids are devastating pests.

              Hardwoods tend to grow on nice sites and have tap roots. They are mostly deciduous in the north but often evergreen in the tropics. They often prefer more basic soils than conifers. Their diverse array of fruits tie them into a wider web of fauna. Many specific broadleaf trees have whole industries built around them from pencils to toothpicks, baseball bats and hockey sticks.

              Many of the broadleaf trees that are native to North America are currently under assault from exotic insect or disease pests! Emerald Ash Borer has killed millions of Ash trees and continues to spread. Gypsy Moths and Sudden Oak Death are affecting Oaks. Dogwood Anthracnose is taking out these iconic small trees. Other species are under attack as well including Butternut (Juglans cinerea) and Red Bay (Persea borbonia). Chestnut Blight and Dutch Elm disease are afflictions of old that have radically changed forest composition in the east.

Woody Plant Indentification

             Flowers or Fruits are always the easiest way to identify a plant in combination with the rest of the characteristics. The first characteristic that i pay attention to elsewise is leaf orientation and whether a plant is opposite or alternate. Opposite leaved plants fall into the pneumonic device MADCapHorseSweetLove

(M) aple (A) sh (D) ogwood (CAP) rifoliaceae including (Adoxaceae) (Horse) Chestnut (Hippocastanaceae)

(Sweet) Bubby (Calycanthaceae) (Love) Heart’s a bustin (Celastraceae)

             Compound versus simple leaves are the next distinguishing trait with woody plant identification especially. Compound leaves are fairly rare and more distinguished depending on leaf orientation. Opposite typically denotes Elderberry (Adoxaceaceae), Ash (Oleaceae) and Maple/Buckeye (Sapindaceae). Woody plants with alternate compound leaves typically fall in the Walnut (Juglandaceae), Rose (Rosaceae) or Bean (Fabaceae) families.

             Leaf margin, hairiness, buds, and scars are additional traits used in dendrological identification. Hariness denoted by such terms as strigose, tomentose, pubescent, hirsute, stellate, pillose etc…are often reason enough for classic species delineation. Winter identification mostly depends on bark, bud type (number/shape of scales) and leaf/vascular bundle scars. We have played winter tree id in the Asheville area to much enjoyment and delight as well as humbled bafflement even in familiar terrain.

            Many great references exist to help one in the exploration of woody plants and their uses (Brockman, 1986; Dirr, 1998; Elias, 1980; Hardin, Leopold, & White, 2001). In Appalachia the references i use most are represented by a handful of books (Petrides, 1998; Radford, Ahles, & Bell, 1968; Swanson, 1994; Weakley, 2008; Wofford, 1989).  Swanson in particular is key!

            In the Sierra’s i have been thankful for a compact lightweight book by Petrides (2005). In the past i have also consulted a bigger more comprehensive resource (Sudworth, 1967).  The Flora of the California is known as the Jepson Manual (Hickman, 1993). A new version is on the verge of publication (Baldwin, Goldman, Keil, Patterson, & Rosatti, 2012). These are the definitive resources to the over 5,000 plant taxa that occur within the Golden state.

Monographs

            Below are monographs for most of the major woody plant families in the temperate world! Families are listed alphabectically by scientific name. Your support to develop this further is greatly encouraged. Factoids and funds could move this along to a more comprehensive place!

            Family descriptions are covered systematically. First, occurs a chart showing distribution in the world, North America and the Blue Ridge using the sources underlined in the introdution above. A modern taxonomic commentary depending on three main sources follows (Heywood et al., 2007; Judd et al., 2008; Weakley, 2008). Next follows a listing of genera known in Appalachia according to Wofford (1989). The number of species for each genus is in parentheses. The first number is for native species. The second number is for introduced species. The introduced species numbers are also highlighted to further show their patterns of distribution. Introduced plants in general tend to be represented by one species from an exotic genus. The native species almost always out number introduced species when contained within the same genus. A list of taxa excluded by Wofford follows.  Excluded taxa are normally reported from a limited range and are often cultivated plants that may escape locally. Within the above three botanical sections all plant names are in scientific terminology only. In the below usage categories common names precede scientific names at least the first time the plant is mentioned i.e. Carrot (Daucus carota). Plant names are capitalized because to me they are at least as important as people.

            Finally species that fit into the categories of food, medicine, poison, insect affiliation, invasiveness, dye plants, other crafts, aesthetics and aromatics are included. Foods included comprise wild and cultivated taxa. One source is the primary reference mixed with over a decade of personal experience (Couplan, 1998). Don’t ever eat flowers or other parts of plants from a florist or other synthetic chemical intensive source. Always be absolutely positive of the identification and utilization  of anything you plan to consume! Medicinal notations are limited to only some extremely important plants due to time limitations.  Invasiveness is only covered relative to Appalachia and specifically inclusion in the Blue Ridge Flora. One cited reference was used primarily (Miller, Chambliss, & Bargeron, 2006). However, personal experience with exotic invasive plants informed commentary that is not cited. Many invasive plants in Appalachia are also invasive throughout their introduced range. Plant uses by bees were compiled primarily from two comprehensive book sources with the addition of eight years personal experience (Lovell, 1977; Pellett, 1977). Dye plants included are noted when not so plentiful to be confusing. For the Asteraceae, Fabaceae, Rosaceae, etc…only some dye plants of special interest are included. Highlighted sections are still a work in progress.

Blue Ridge Genera: Toxicodendron (3), Rhus (4)

Food: Fruits of Sumac (Rhus spp.) have been used by Native Americans and others to make a type of pink lemonade due to malic acid. Many popular exotic food stuffs are in this family. These include Pistachio (Pistacia spp.), Cashew (Anacardium occidentale), Mango (Mangifera indica), and Brazilian pepper (Schinus spp.).

Toxicity: Poison Ivy (Toxicodendron radicans), Poison Oak (T. toxicarium), Poison Sumac (T. vernix) can cause severe skin irritation for susceptible individuals. Allergic reactions are known to occur for certain people with many if not all the members of this family!

Insects: Bees freely work Rhus spp. for nectar.

Invasiveness: Poison ivy is native but can quickly take over disturbed areas.

Dye Plants: Smoketree (Cotinus coggygria), Sumacs (Rhus copallina, R. copallinum, R. coriaria, R. glabra, R. hirta, R typhina) (Bliss, 1993; J. Cannon & Cannon, 2003; Fern, 2008; A. Krochmal & Krochmal, 1974; Moerman, 1998; Nicholson & Clovis, 1967)

Aesthetics: Fruits of Rhus spp. make great additions to flower arrangements fresh or dry. Cotinus is a beautiful landscape plant that can also be employed in flower arrangements to striking effect.

Taxonomic commentary: Nemopanthus has now been moved to Ilex (Heywood et al., 2007).

Genera: Ilex (4), Nemopanthus (1)

Food: The roasted leaves of some members have been used to prepare a caffeinated beverage including Yerba Mate (Ilex paraguariensis) and Yaupon Holly (I. vomitoria) (Couplan, 1998).  Ilex cassine and I. guayusa also have significant amounts of caffeine (Edwards & Bennett, 2005; Wink & Van Wyk, 2008).

Toxicity: Triterpine saponins and their esters (Wink & Van Wyk, 2008). The berries are not edible. However, the leaves tend to be not toxic (Nelson, Shih, & Balick, 2007).

Insects: Gallberry (Ilex glabra) is important for bees in warmer areas (Pellett, 1976). Many other species of Ilex are good sources of nectar as well.

Invasiveness: None known

Dye Plants: American Holly (Ilex opaca)

Other Crafts: Ilex spp. have traditionally been use for wood work.

Aesthetics: Many species are very attractive in the landscape for evergreen foliage and showy fruits. Plants are dioecious so males and females are required for fruiting.

Genera: Aralia (4), Hedera (1), Panax (2)

Food: The leaves and roots of Sarsparilla (Aralia californica) are used by Daniel Nicholson in California for tea. This is the only native member of Araliaceae in the state . Other members of Aralia from the Eastern U.S. have been used similarly especially in the preparation of root beer. Some young shoots of Aralia spp. have been eaten in the spring.

Medicine: Multiple species of Panax are adaptogenic (Winston & Maimes, 2007) Aralia spp. may be medicinal as well.

Toxicity:  Triterpine saponins occur in the Araliaceae including English Ivy (Hedera helix) (Wink & Van Wyk, 2008). Hedera helix may also cause contact dermatitis (Nelson et al., 2007). Members of Aralia may cause irritation to susceptible individuals especially if consumed raw.

Insects: Insects love members of this family in bloom.

Invasiveness: English ivy (Hedera helix) is a fierce exotic invasive.

Dye Plants: Hedera helix (Cannon, 1994; Fern, 2009).

Other Crafts: Vines of ivy can be used for various decorations.

Aesthetics: Hedera helix is famous for covering buildings but can cause some damage to the outside surface. Many Aralia spp. are beautiful plants with showy blossoms. Devil’s Club (Oplopanax horridus) is stunning in the understory of the Pacific Northwest confier forests.

Blue Ridge Genera: Berberis (2), Caulophyllum (2), Diphylleia (1), Jeffersonia (1), Podophyllum (1)

This is a mostly vegetative family with one prominent shrubby member (Berberis) and a host of medicinal uses.

Food: The edible berries are sour and often need to be sweetened in the Barberry (Berberis) and cultivated Oregon grape (Mahonia) genera. Fruits of Mayapple (Podophyllum peltatum) may be consumed when fully ripe.

Medicine: Blue Cohosh (Caulophyllum thalictroides) is a potent medicine for women’s issues. Berberine contained in many members is a potent medicine. Podophyllotoxin is a powerful anti-cancer drug (Duke & Foster, 1999).

Toxicity: This family tests the boundaries between food, medicine and poison. Blue Cohosh (Caulophyllum thalictroides) contains an alkaloidal convulsant poison (Nelson et al., 2007).  Podophyllum contains a mitotic inhibitor (Nelson et al., 2007).

Insects: Berberis spp. are attractive to bees but rarely provide much honey.

Invasiveness: The exotic Japanese Barberry (Berberis thunbergii), Beale’s Barberry (Mahonia bealei) and Heavenly Bamboo (Nandina domestica) all can be invasive (Miller et al., 2006).

Dye Plants: Many species of Barberry (Berberis spp.) and Oregon Grapes (Mahonia spp.) can be used for dyes (Bliss, 1994; Cannon, 1994; Fern, 2009; A. Krochmal & C. Krochmal, 1974).

Aesthetics: The flowers of Oregon grape are often showy and slightly fragrant. The fruits of various Barberries and Oregon grapes are attractive. Though spiny, they can be used in flower arrangements.

Food: Nuts from Corylus including the European Filbert (C. avellana) and the American Hazelnut (Corylus americana). The inner bark of the Alder was eaten by Native americans as a survival food (J. Pojar et al., 1994).

Medicine: Alder was a typical medicine for the Native people of the Pacific Northwest (J. Pojar et al., 1994).

Toxicity: ?

Insects: Alders (Alnus spp.) are an important early source of pollen for bees.

Invasiveness: None known

Taxonomic commentary: The Caprifoliaceae is a messy family in transition. Elderberries (Sambucus spp.) and Viburnums (Viburnum spp.) have often been moved to Adoxaceae. A number of genera have sometimes been given their own families i.e. Sambucaceae, Diervillaceae, Linnaeaceae (Heywood et al., 2007). American Elderberries have been changed to subspecies of the European one i.e. (Sambucus canadensis) to (Sambucus nigra spp. canadensis) (Weakley, 2008).

Blue Ridge Genera: Diervilla (3), Linnaea (1), Lonicera (3,3), Sambucus (2), Symphoricarpos (2), Triosteum (3), Viburnum (9) Wofford excluded: Lonicera fragrantissima and Lonicera xylosteum

Food: Fruits from Black Elderberry (Sambucus nigra ssp. canadensis) Blue Elderberry (Sambucus nigra ssp. cerluea) are used for jelly, wine, syrup etc. Some black fruited Viburnums are edible raw (V. cassinoides, V. alnifolia, V. lantana, V. nudum, V. prunifolium) and red fruited Viburnums are best cooked (V. trilobum, V opulus) (Couplan, 1998). Fruits from the horse gentian (Triosteum perfoliatum) can be roasted as a coffee substitute (Couplan, 1998)

Medicine: Sambucus nigra ssp. canadensis is a famous medicine for colds and flu. Japanese Honeysuckle (Lonicera japonica) is a prevalent flue remedy in China used as part of the formulation Yin chiao. Crampbark (Viburnum opulus) and Black Haw (Viburnum prunifolium) have a long history of use for women’s health.

Toxicity: Sambucus contains cyanogenic glycocides and only the stem less fruits should be consumed. Snowberry fruits (Symphoricarpos spp.) contain saponins and a small amount of chelidonine (Nelson et al., 2007).

Insects: Blackhaw (Viburnum prunifolium) is good for stimulating early brood production. Sambucus nigra ssp. canadensis is important for pollen. Most Lonicera spp. flowers have tubes too long for bees to reach their nectar. However, some bush and fly honeysuckles (L. morrowi and L. tatarica) are visited by bees. Coralberry (Symphoricarpos orbiculatus) is much sought after by bees when abundant.

Invasiveness: Seven taxa of Honeysuckle (Lonicera spp.) are introduced and invasive to various degrees though a few are not included in Wofford (1989). These include (L. japonica), Breath of Spring (L. fragrantissima), Morrow’s Honeysuckle (L. morrowii) Coral Honeysuckle (L. sempervirens), Standish’s Honeysuckle (Lonicera standishii) Tatarian Honeysuckle (L. tatarica) and Bell’s Honeysuckle (L. X bella) (Miller et al., 2006).

Dye Plants: Elderberries (Sambucus spp.) (Cannon, 1994; Fern, 2009; A. Krochmal & C. Krochmal, 1974; Nicholson & Clovis, 1967).

Other Crafts: The exotic invasive Lonicera japonica can be used for basketry (Hill, 1997).

Aesthetics:  Many species are attractive ornamental plants and smell wonderful.
