Peak flowering noted during the last week in April (central Iowa, 2023). Originally located and vouchered (ISC) by Jimmie D. Thompson. As of 2023, the current Iowa Department of Natural Resources list of Endangered, Threatened, and Special Concern species currently has Amelanchier humilis in Iowa listed as 'no status'. Initiated in 2021, an endangered plant scientific advisory group was assembled to review floristic surveys and herbarium specimens and through group discussion update or assign a recommended status for nearly 400 rare plant species. The current (2023) recommended status of Amelanchier humilis for Iowa is Threatened. | 2158158 | Ames 36123 |
