Purple Flowering Raspberry (Rubus odoratus)
The Rubus spp. is a wildlife rockstar in general. Although I could not find a ton of species-specific information, I assume Purple Flowering Raspberry has many of the same attributes. Its big, attractive, rose-like flowers attract a variety of native bees, butterflies, and skippers (illinoiswildflowers.info). It is the host plant to 156 species of butterflies and moths (Johnson and Colla, 2023) (nwf.org), including a species of concern, the Yellow-Banded day-sphinx (mnfi.anr.msu.edu). Purple Flowering Raspberry is an attractive shrub that is thornless, has nice foliage, and edible berries (though they are not as good as their cousins that you see in the grocery store) that birds seem to enjoy. This awesome plant is thicket-forming and is best suited for those partly shaded areas where it is allowed plenty of room to spread, so choose your spot wisely. It is partially self-fertile, but does better with more plants around.
