| 19 | NA 82343 | NA 82343 | Bidens polylepis S. F. Blake | | NA | | Not Available | 2023 | | | | | | | Uncertain improvement status | Full name as recorded at U.S. National Arboretum: Bidens polylepis. Spontaneous in the Fern Valley meadow (and throughout meadows and open areas across much of the USNA grounds). Possibly derived from NA 52683 (R. C. Brewer ex Am. Hort. Soc.), which was sown in the Fern Valley meadow in the early 1980s. This is uncertain and there is a good possibility that other germplasm has also been intermixed, so a new number is needed. Form received: existing plant. | 2152888 | NA 82343 |
