false indigo, Amorpha fruticosa

False indigo flowers don't look much like something from the pea family. On the other hand, if you see non-flowering shrubs you would be hard pressed to say they're nor black locust. These kind-of-strange, kind-of-pretty flowers are often planted. I suspect that's as much because they're kind-of-strange as it is for their beauty. When I planted them here, they were not much appreciated by those who didn't appreciate strange (the rest of the family). This subshrub grows in every state except AK, HI, and NV, and in MB, NB, ON, and QC. It was introduced in the northwest and northeast parts of that range, as well as Eurasia. Lenawee Co MI, 6/15/11.
