Nees | Maryland, United States | NA | | Not Available | 2022 | COLLECTED | 09/04/2022 | Plants growing at Elkton State Forest along roads and woodlands over a distance of approximately 5 kilometers labelled as the address of 717 Irishtown Rd, North East, MD 21901. Plants are found regularly along the unnamed gravel road. | 39.58863200, -75.90452800 | 63 | Plants are growing in a mesic to dry, well-drained habitat of mixed deciduous and evergreen woodlands comprised primarily of acid-loving plants. Plants are growing in part shade to sun. The soils in the collection area are generally described as a complex series of fluviomarine deposits. The soils range from a thin loam layer at the surface to varying levels of loam to sandy loam and/or extremely gravelly sandy clay loam strata, depending upon geographical location (ie. Hillslope summits, slopes, footslopes, swales, etc.). The primary soil types in the collection area are classified as Russett-Christiana-Hambrook Complex and/or Sassafras and Croom Soils; though, others may intersect and overlay in specific areas. | Wild material | | 2139365 | NA 88486 |
| 4 | Ames 35740 | Iroquois County Conservation Area | Sassafras albidum (Nutt.) Nees | Illinois, United States | NC7 |  | Not Available | 2021 | COLLECTED | 08/27/2021 | Iroquois County State Wildlife Area located approximately 4.5 miles northeast of Beaverville T29N R11W NE1/4 Sec. 22 and also NW1/4 Sec. 13 | 40.98890900, -87.58503400 | 195 | Edge of hardwood forest, along roadside. | Wild material | Sassafras albidum is an early successional, vigorously suckering native tree found throughout southeastern North America stretching from eastern Texas to Maine. In Illinois, the species is only found in the southeastern portion (two-thirds) of the state. Sassafras is found in nature typically in dry to slightly mesic woodland edges and fencelines. Sassafrass is dioecious where male and female flowers are on separate plants. Noteble characteristics include oddly shaped leaves; a wide vareity of attractive fall colors (red, orange, or yellow); and stems that have an attractive spicy odor when scratched. Highly prized fruits by birds are single-seeded black drupes with bright red pedicels that mature in late summer. This accession was collected on the northwest edge (USDA Cold Hardiness Zone 5b) of the species range and may potentially contain genetics for winter hardiness exceeding that of typical Sassafras. Specimens sampled in nature ranged from 20-40' in height and 5-8" d.b.h. and the percentage of specimens suspected to be of reproductive age actually noted with fruits at the time of sampling (2021) was estimated at only 5-10%. It is possible that pollination on other potentially female specimens did not occur. During a grow out of seedlings at the North Central Regional Plant Introduction Station in Ames, Iowa in 2022, fall color on potted specimens peaked the first week in October. In comparison to Ames 35741, genetics of this accession peaked color 5-7 days prior and seedlings originating from sample 982-3 were all reddish in color, while seedlings from all other samples (982-1 and 982-2) were a mix of yellow; yellow-orange; and reddish-orange. | 2120344 | Ames 35740 |

This accession was collected on the extreme northwest edge (USDA Cold Hardiness Zone 5b) of the species range and may potentially contain genetics for winter hardiness exceeding that of typical Sassafras. Specimens sampled in nature ranged from 20-60' in height and 5-12" d.b.h. and the percentage of specimens suspected to be of reproductive age actually noted with fruits at the time of sampling (2021) was estimated at only 5-10%. It is possible that pollination on other potentially female specimens did not occur. A few specimens noted lacked the characteristic lobing of the leaves. During a grow out of seedlings at the North Central Regional Plant Introduction Station in Ames, Iowa in 2022, fall color on potted specimens peaked the first week in October. In comparison to Ames 35740, genetics of this accession peaked color approximately 5-7 days later. All seedlings displayed fall colors ranging from yellow; yellow-orange; and reddish-orange. | 2120345 | Ames 35741 |
