Shade Tree (over 40’) Deciduous Kentucky Coffeetree (Gymnocladus dioica) Plant Pages: Native Family: Fabaceae Trees & Shrubs Map #45 Leaves: bipinnately compound, up to 3 feet long and 2 feet wide, leaflets 2-3 inches long, margins smooth, base of petiole swollen; fall - yellow, usually not good. Buds: alternate, sometimes one bud directly above another at the node, brown, slightly hairy, sunken and scarcely projecting beyond the twig, sur- rounded by downy golden rim of bark, terminal bud is absent. Stems: stout, very coarse, smooth and shiny or downy, pith large in di- ameter and salmon pink colored. Bark: recurved (curved backward), spoon-like depressions, gray brown . Flowers: usually male plants and female plants, greenish white, borne in 8-12” panicles (female), male panicle about 1/3 the length of the female, female flowers fragrant. Fruits: on female plants only, reddish brown, leathery pod, 5-10 inches long, containing a few, large blackish brown seeds imbedded in a sticky pulp, persistent through winter into early spring. Habit: narrow oval but much variation. Culture: Although it prefers moist, well-drained, high pH soils in full sun, the coffeetree is adaptable to urban conditions, tolerating drought and pol- lution. There are no serious insect or disease problems on this species. Because of its cultural adaptability and trouble-free character, coffeetrees make ideal specimens for streets or parks. Because of their tendency to litter, this species is probably best sited in areas where a manicured im- pression is not important. Male selections are now available to avoid fruit production.

Gymnocladus Dioicus Characteristics This Perennial Tree Is a Member of the the Kentucky Coffeetree Legume Or Fabaceae Family
Gymnocladus Dioicus Characteristics This perennial tree is a member of the The Kentucky Coffeetree legume or Fabaceae family. The term Gymnocladus By Dominic Sandy means “naked branch” which refers to its ugly, naked appearance during the winter months. The term dioicus refers to the fact that the tree is dioecious in nature, meaning the male and female flower parts are on separate trees. If in an open area with lots of sunlight, the tree can grow to heights of 80 feet and widths of 50 feet. The trunk is rather thin for its size, reaching diameters of only 1 to 2 feet. The Leaves The leaves are bipinnately compound and are http://campus.murraystate.edu/academic/faculty/hwhiteman/Field/ extremely large, reaching up to 3 feet long. The plants/kcoffee.html leaflets are arranged alternately to structures The Gymnocladus dioicus, otherwise known called rachilla, which are oppositely arranged on as the “Kentucky Coffeetree”, is native to much of the rachis. Leaflets are fairly small, not toothed and the Midwestern United States and very prevalent pointed at the apex. They grow extremely slow and in western Ohio. At maturity, the tree stands as a don’t emerge until late spring and fall during early true beauty but has an awkward appearance autumn. Since a large portion of the year, there is during the early growing years. It is very slow- no leaves, the tree looks naked and dead while growing but at maturity can reach upwards of 80 other trees are in bloom. When the leaves fall, feet tall. The female tree’s produce a fairly large, they leave very large and noticeable scars on the pod-like fruit containing seeds which can be eaten stems.

Fertilization is the union of the (male) sperm nucleus from the pollen grain and the (female) egg nucleus found in the ovary. If fertilization is successful, the ovule will develop into a seed and the ovary will develop into a fruit. Seed Characteristics Seed coats are the hard outer covering of seeds. They protect seed from diseases, insects and unfavorable environmental conditions. Water must be allowed through the seed coat for germination to occur.

Evaluating Revised Biomass Equations: Are Some Forest Types More Equivalent Than Others? Coeli M
Hoover and Smith Carbon Balance Manage (2016) 11:2 DOI 10.1186/s13021-015-0042-5 RESEARCH Open Access Evaluating revised biomass equations: are some forest types more equivalent than others? Coeli M. Hoover* and James E. Smith Abstract Background: In 2014, Chojnacky et al. published a revised set of biomass equations for trees of temperate US forests, expanding on an existing equation set (published in 2003 by Jenkins et al.), both of which were developed from published equations using a meta-analytical approach. Given the similarities in the approach to developing the equa- tions, an examination of similarities or differences in carbon stock estimates generated with both sets of equations benefits investigators using the Jenkins et al. (For Sci 49:12–34, 2003) equations or the software tools into which they are incorporated. We provide a roadmap for applying the newer set to the tree species of the US, present results of equivalence testing for carbon stock estimates, and provide some general guidance on circumstances when equation choice is likely to have an effect on the carbon stock estimate. Results: Total carbon stocks in live trees, as predicted by the two sets, differed by less than one percent at a national level. Greater differences, sometimes exceeding 10–15 %, were found for individual regions or forest type groups. Dif- ferences varied in magnitude and direction; one equation set did not consistently produce a higher or lower estimate than the other. Conclusions: Biomass estimates for a few forest type groups are clearly not equivalent between the two equa- tion sets—southern pines, northern spruce-fir, and lower productivity arid western forests—while estimates for the majority of forest type groups are generally equivalent at the scales presented.

A Very Successful Garden Center Stately Manor Kentucky Coffeetree
Stately Manor Kentucky Coffeetree Gymnocladus dioicus 'Stately Manor' Height: 50 feet Spread: 30 feet Sunlight: Hardiness Zone: 4a Description: A stately large shade tree with massive yet delicate multiply compound leaves; narrow habit of growth, rather coarse outline when young and in winter, but very attractive when in leaf; tolerant of adverse growing conditions, a seedless variety Ornamental Features Stately Manor Kentucky Coffeetree Photo courtesy of NetPS Plant Finder Stately Manor Kentucky Coffeetree has forest green foliage throughout the season. The large bipinnately compound leaves do not develop any appreciable fall color. Neither the flowers nor the fruit are ornamentally significant. The rough dark brown bark adds an interesting dimension to the landscape. Landscape Attributes Stately Manor Kentucky Coffeetree is a deciduous tree with an upright spreading habit of growth. Its strikingly bold and coarse texture can be very effective in a balanced landscape composition. This is a relatively low maintenance tree, and is best pruned in late winter once the threat of extreme cold has passed. It has no significant negative characteristics. Stately Manor Kentucky Coffeetree is recommended for the following landscape applications; - Shade Planting & Growing Stately Manor Kentucky Coffeetree will grow to be about 50 feet tall at maturity, with a spread of 30 feet. It has a high canopy with a typical clearance of 6 feet from the ground, and should not be planted underneath power lines. As it matures, the lower branches of this tree can be strategically removed to create a high enough canopy to support unobstructed human traffic underneath. It grows at a slow rate, and under ideal conditions can be expected to live for 90 years or more.

PURDUE EXTENSION Hardwood Lumber and Veneer Series Coffeetree FNR-281-W Daniel L. Cassens, Professor and Extension Wood Products Specialist Department of Forestry and Natural Resources, Purdue University, West Lafayette, IN 47907 Coffeetree (Gymnocladus dioicus (L.) K. Koch) or Kentucky coffeetree, is an occasional tree ranging mostly from central Ohio to southern Michigan and Wisconsin to eastern Kansas south to Oklahoma and back to northern Kentucky. There are several isolated pockets of the species outside of the range given above. The tree prefers rich, moist woods, and it is intolerant of shade. The tree is medium sized to large and can reach 100 feet in height. The largest reported tree is about 5.4 feet in diameter at 4½ feet above the ground. Wood Color and Texture The sapwood is a yellowish white and narrow. The heartwood is a reddish brown or reddish orange with a very prominent but straight grain pattern on flat sawn stock. The wood is ring porous like the oaks with the large pores plainly visible. The wood of the coffeetree is sometimes confused with honey locust. Workability Coffeetree is relatively dense and firm, and the wood has good working properties. Strength The wood weighs about 42 pounds per cubic Chip Morrison foot or nearly as much as oak. Limited available A Cassen’s coffeetree information indicates the wood is similar in strength to the red oak group. Drying Steam Bending Specific information on drying schedules is not No information is available. available. The author has not seen serious drying defects in coffeetree wood, and it will probably not present serious problems in drying.

A Comprehensive Seed Collection of the Kentucky Coffeetree, Gymnocladus Dioicus (L.) K
Proceedings of Workshop on Gene Conservation of Tree Species—Banking on the Future From Forest to Freezer: a Comprehensive Seed Collection of the Kentucky Coffeetree, Gymnocladus 1 dioicus (L.) K. Koch A.P. Schmitz2 and J.D. Carstens3 Kentucky coffeetree, Gymnocladus dioicus, is a picturesque shade tree adaptable to urban conditions and drought, with no serious insect or disease problems. These traits make G. dioicus a promising candidate among diverse tree genera to replace ash (Fraxinus) trees affected by the emerald ash borer (Agrilus planipennis) or oaks (Quercus) being affected by oak wilt (caused by the fungus Ceratocystis fagacearum) within our cities. In nature, Kentucky coffeetree comprises only a small percentage of forested systems across the Midwest, warranting the assembly of an ex situ germplasm collection. Collaboration between The Brenton Arboretum and the North Central Regional Plant Introduction Station has resulted in the acquisition and preservation of one of the most comprehensive ex situ woody plant seed collections represented in the United States National Plant Germplasm System and an extensive G. dioicus living plant collection at The Brenton Arboretum. To date, 80 georeferenced sites in 12 of the 14 states within the core native range of G. dioicus have been sampled. Targeted sites were systematically selected focused on Omernik Level III Ecoregions followed by geographic gaps. This targeted approach along with the sampling of multiple genets within a population strives to ensure the assembly of a genetically heterogeneous collection adaptable to a wide-range of climatic factors. Our efforts have documented the natural occurrence of this species along with its habitat and associated vegetation, soil type, plant health, rarity, and regeneration.
