Please try our next iteration of the Michigan Flora Online here. Beginning on February 1, 2023, michiganflora.net will point to this new site.

The new site offers several benefits over the existing website, including real coordinate mapping, giving a clearer view of the density of documentation as well as more precision about plant distributions and their link to landforms. We will also have the ability to update species pages more regularly, both in terms of new collections and as more existing Michigan specimens are georeferenced. In addition, we have a better photo display, and offer indented keys.

Hackelia deflexa (Wahlenb.) Opiz
Common Name: STICKSEED
Coefficient of Conservatism: 2
Coefficient of Wetness: 5
Wetness Index: UPL
Physiognomy: Nt B-Forb

Deciduous forests, especially along borders, trails, and clearings; on shores and bluffs; dune thickets and rocky sites.

Eurasian plants differ slightly from our native American ones, which are var. americana (A. Gray) Fernald & I. M. Johnst., also known as H. americana (A. Gray) Fernald.

Plants with leaves as wide (very rarely) as 5 cm are robust ones (a meter or more tall), while plants of H. virginiana with leaves as narrow as 2.5 cm are small, delicate ones. The difference in flower color is consistent on Michigan material, although as in any blue-flowered species white-flowered individuals of H. deflexa might occur.
