Please try our next iteration of the Michigan Flora Online here. Beginning on February 1, 2023, 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.

Lilium philadelphicum L.
Common Name: WOOD LILY
Coefficient of Conservatism: 7
Coefficient of Wetness: 0
Wetness Index: FAC
Physiognomy: Nt P-Forb

Open sandy or rocky ground, dunes, sandy open forests (jack pine, aspen), edges of coniferous forests, in fens; often thriving along grassy roadsides and in clearings.

One of our finest wildflowers. Plants may have as many as 5 flowers (very rarely -7), although fewer (often only 1) are usual. The flowers are normally orange to nearly red, but the yellow-flowered form [f. flaviflorum E. F. Williams] has been found very rarely in Michigan. A form with the tepals unspotted as well as yellow [f. immaculatum Raup] has been collected at West Bluff in Keweenaw Co.
