October is not a great month for flowering, but a few plants flower in the fall. This little perennial is generally hard to raise, at least for us (it keeps dying) but the right combination of shade and water seem to be keeping it happy. It's commonly called a toad lily (a species of
Tricyrtis). The perianth is decorated with pinky-purplly spots as is the three branched style. It stands about 12" tall with about 1" diam flowers. It is not a native, but also is not invasive. It started flowering on the 5th of October.
