Soils rather mucky/heavy clay. | Wild material | Native to North America, this deciduous tree has a native range that covers the Atlantic coastal plain concentrated in the Carolinas and also along the Mississippi and Ohio Rivers along with various, tiny disjunct populations widely scattered across the southeast U.S. (Little, 1971). As an obligate wetland plant, the soils that this species inhabits is typically heavy clay (ranging 24 to 65%) and slightly acidic (soil pH ranges from 4.6 to 5.9) (Johnson 1990). Typical habitat is bottomlands/floodplains that generally have standing, shallow water. Sites that are often too wet for P. deltoides are suitable for P. heterophylla. Swamp Cottonwood can reach 10-20 meters in height and generally has an upright, rounded form. Broadly ovate leaves are rather large reaching up to 25 cm in length and nearly 15 cm wide with abaxial surfaces usually pubescent to partially glabrate. As with many other species in Salicaceae, P. heterophylla is dioecious with staminate and pistillate catkins appearing in early spring and reaching up to 10 and 15 cm in length, respectively. Seeds are dispersed in spring through early summer. Swamp Cottonwood is distinguishable from other Populus largely due to the distinctly cordate leaf bases and distinctive orange-brown pith in young twigs (McMaster 2003). Ornamental characteristics include golden yellow fall color. This taxon is essentially non-existent in the nursery trade and extremely rare in botanical garden and arboretum collections. Due to this species ability to grow in anaerobic, soils heavy in clay, this species may perform well in the typical urban landscape. Its potential to withstand extreme, drought despite being an obligate wetland plant may be similar to that found in Taxodium distichum. Genetics of this accession were collected in southern Indiana. Specimens sampled in nature were approximately 40-50' in height and were clonally (vegetative) spreading by rhizomes. | 2158343 | Ames 36138 |

Simmers. Described as a broad-leaved form of M. fistulosa, generally intermediate between M. fistulosa and M. clinopodia, with probable hybrid origin. Typcial habitat is mesic woods and edges on lowlands. In contrast to M. fistulosa, this taxon has longer petioles (usually 2-3 cm versus 0.5-2.0 cm), lower leaf surfaces with scattered spreading hairs, and corollas are paler pink at tips to almost white with peak flowering occurring prior to M. fistulosa by approximately 1-2 weeks. Leaves are rather rugose, where upper leaf tissue between veins is visibly raised. This accession represents genetics from northern Indiana (Potato Creek State Park). Plants at the collection site in nature peaked flowering near 8 July 2019 where flower colors were more lavender in sun but pale in shade (Namestnik, S., personal communication, 15 July 2020). Peak fruiting occurs mid-August. Average height of plants sampled in nature estimated at 4.5' in height. | 2097752 | Ames 35216 |

Rocky substrate. 20 degree northwest-facing slope | Wild material | Ulmus thomasii (Rock elm) is an underutilized tree species both in conservation and in the urban landscape. Charles Sprague Sargent (first director of the Arnold Arboretum of Harvard University, Boston, MA) described the wood of Rock Elm as "heavy, hard, very strong and tough, closely grained, and susceptible of receiving a beautiful polish". Historically noted for a variety of uses in woodworking including furniture, heavy agricultural implements, timber frame buildings, pianos, hockey sticks, and hand tools. U. thomasii is extremely drought tolerant, adaptable to very calcareous soils, and compared to U. americana or U. rubra has a very conservative growth rate requiring minimal attention in regards to pruning. Rock elm naturally tends to develop into a nice structural specimen in the landscape, unlike other fast growing U. americana cultivars in the nursery trade needing frequent attention. Rock elm has very fissured bark and is well known for maintaining a strong central leader resulting in a very attractive, pyramidal form. Despite many literature sources stating that "wings" on the stems are a key identifiying characteristic, this trait is not reliable and many genotypes may completely lack "wings" on the stems. While growth habit and morphology of dormant buds (very pointy) are good traits to help aid in identification, fruits are the best way to confirm identity. Fruits are densly pubescent, often described as "inflated" and generally reach maturity a couple weeks after U. rubra and U. americana. U. thomasii flowering in central Iowa typically occurs the last week in April into the first week in May and are rather distinguishable from other Ulmus in being pendulous. Fruits are extremely prized treats for many birds, where fruits are often "robbed" prior to full maturity. Fruits are also highly prized by many other animals such as mice, squirrels, chipmunks, turkeys, etc. and are generally consumed within hours after fruit abscission. The native range of U. thomasii is concentrated in the northeastern United States and into Canada with disjunct populations documented in northwestern Missouri and northwestern Arkansas (Little, E. L. Jr. 1971). In the 1895 Silva of North America (vol. 7) it was stated that, “The value of the wood of the Rock Elm threatens its extinction and most of the large trees have already been cut.” Today, since rock elm is rather rare, especially in areas near the edges of its range, many states list the species as endangered or threatened warranting preservation efforts. This accession represents genetics from northeast Iowa (Winneshiek County). In an assessment of some of the largest Ulmus thomasii (native and cultivated) across Iowa, four of the nine largest specimens in Iowa are present in Malanaphy Springs State Preserve where this accession was sampled. The second largest U. thomasii in the state located in Malanaphy Springs was measured on 22 May 2020 with a circumference of 6.42', height of 86.58', and an average crown spread of 68.00' (180 points) (Rouw, M., personal communication, 8 February 2021). | 1940580 | Ames 33357 |

Kentucky coffeetree is a picturesque shade tree that is extremely tolerant to highly alkaline and also slightly acidic soils, tolerant to both extreme drought and flood events, and has 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) (Schmitz & Carstens 2017). Specimens at the collection site in nature averaged (n=7) 14.50” DBH and 53’ in height (Individual Tree measurements (DBH/Height): #1 = 13"/40', #2 = 15"/50', #3 = 14"/40', #4 = 15"/50', #5 = 13"/30', #6 = 16"/90', and #7 = 15"/70'). Sampling in 2010 estimated more than one hundred genetically distinct trees – the most coffeetrees noted in any single area observed throughout the species native range (Schmitz & Carstens 2018). A return site visit in 2016, estimated that three-quarters of the coffeetrees were dead or in decline after becoming overgrown by hops (Humulus sp.), a result of major flooding events in 2013 and 2014 where floods in 2013 persisted for nearly three months. Flood stage for this population of coffeetrees in the NW ¼ of Sec. 1 resides at 538 MSL (Mean Sea Level) which can be compared against data from the Mississippi River Lock and Dam 17 (Flood Events 2009-2024), where water levels were recorded 14' above ground level where multiple trees of Ames 30493 were sampled. | 1831352 | Ames 30493 |

In cultivation, fall color seems to vary from year to year ranging from dark purplish to bright red with peak fall color occurring around the later part of October (central Iowa). Flowers are white with peak flowering occurring in early-mid May. The range of this North American native is noted throughout the eastern and southeastern U.S. This accession represents genetics from the extreme northwestern corner of the species native range. Viburnum prunifolium in Iowa is rather rare and generally restricted and more commonly found in the extreme southeast corner of the state. This disjunct population in Taylor County (southwest Iowa) has been questioned as to whether it is a true native population or a naturalized escape. Additional V. prunifolium elsewhere in southwest Iowa has not been reported/documented. Immediately to the south of Taylor County, V. prunifolium is documented throughout most of Missouri and thus it is suspected that these genetics do represent a true native population. | 1708694 | WLP 2487 |
