Native to eastern North America, rough avens (Geum laciniatum, Rosaceae) is particularly common in wet and moist areas. It can be found near ponds and ditches, in floodplain forests and damp woodlands, and in other areas with sufficient shade and water. I found this individual in a low tree-dotted meadow here in southeast Michigan.
Avens species are closely related to strawberries (Fragaria spp., Rosaceae) and rough avens in particular bears some notable similarities. Like strawberries these plants features trifoliate (three-part) leaves. The white, five-petaled flowers also look similar to the flowers of strawberries, but rough avens flowers have petals that are greatly reduced. They still manage to attract their fair share of insect pollinators when they bloom in May and June. Once pollinated they develop into some rather interesting fruit that persist into autumn.
Unlike strawberries, rough avens bears fruit that are spheres of hooked spikes rather than succulent red fruit. The unique appearance of the fruit helps distinguish rough avens from other avens species, as do the densely hairy stems.
