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.

Salix purpurea A. A. Reznicek

A European willow originally grown in this country for basket-making, locally well established as an escape from cultivation, especially on lake shores, riversides, and wet banks and ditches.

The leaves tend to be opposite or nearly so, except on vigorous new shoots. Herbarium specimens are sometimes confused with S. pedicellaris; in addition to the habitat distinction and position of the leaves, S. purpurea has a distinctive purplish color to the foliage, the leaf margins are obscurely toothed toward the apex, and the axillary buds are (3–) 5–13 mm long on sprouts.
