This southeastern diploid (2n = 14) is concentrated around the lower Mississippi Valley, and often known as A. canadense var. mobilense (Regel) Owenby; see also Sm and W. It has been reported from relatively dry open habitats in much of Mo., in s. Ill. and rarely in c. Tenn. (Quaterman #1666 at VDB). However, the taxon remains unverified in Ky. and Ind.., where treatments have been somewhat inconsistent (FNA 26, K, W, Ch+). It was reported from w. Ky. by BA, but apparently based on misidentified colls. of ampeloprasum (SIU). In mutabile the inflorescences mostly contain just normal perfect flowers, but sometimes mixed with asexual plants, suggesting polymorphic populations. In typical canadense most or all of the inflorescences contain just asexual bulblets. Also, the flowers of mutabile tend to be slightly deeper pink on ascending pedicels (versus sinuous). There is a more robust midwestern relative with large, often pinkish inflorescences, A. lavendulare J.M. Bates, which is also usually considered just a variety of canadense. That taxon has been widely distributed through Prairie Moon Nursery in Minn. and others; it may be sometimes cultivated as a supposed native plant in Ky. In FAYE during 2017, some plants of this taxon were flowering and seeding as late as Nov. More distantly related species from western states may also be cultivated in Ky. but are not know to spread by seed. These include A. amplectens Torr. or its close relatives (FNA 26), especially the white-flowered cultivar "Graceful [Beauty]" (pacificbulbsociety.org). Identification can be difficult; see also notes under senescens ("German garlic") and tuberosum ("garlic chives").
