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.

Crocosmia ×crocosmiiflora (Lemoine) N. E. Br.
Common Name: CROCOSMIA
Coefficient of Conservatism: *
Coefficient of Wetness: 0
Wetness Index: FAC
Physiognomy: Ad P-Forb

This very showy garden hybrid of two South African species (Crocosmia aurea × C. pottsii) is regularly cultivated and relatively hardy in southern Michigan. Collected in 2016 in Ottawa Co. by W. S. Martinus in rich soil along the Grand River at the drier upper boundary of a disturbed marsh, near the edge of the transition to upland forest. 

This hybrid entity does not produce seed, but can apparently spread vegetatively by cormlets produced in the inflorescences and on the corms, and is considered invasive in some areas of warmer climates than Michigan (e.g., New Zealand).
