Description

When I stepped out into the dark, I felt a soft lump. No shoes were involved. We both survived without serious injury. Toad moved to opposite side of doorway. I apologized. I feel tolerated, but not accepted and will never be sure if I've been forgiven. That is fair. Be well, Toad.

There was a toad at the door the previous night as well, maybe the same?

Downy hairs on stems and leaves. Leaf tips apiculate. Last photo shows plant’s habitat, emerging at the base of a wall along the north side of an alley and flowering from underneath the pod of a Kentucky Coffeetree. The growth seems most vigorous against surfaces that hold warmth, including the wall, the concrete, and the dark-colored seed pod.
