When the native clematis blooms, I know that it is late summer. This native plant blooms in time to catch the fall migration of butterflies. The butterflies and bees and flies polinate the clematis. The butterflies lay their eggs on the clematis. The clematis dies usually before the killing Autumn frost. The life cycle continues. I find this native vining plant beautiful with its small white blossoms. On the other hand, this plant can be an invasive weed. With the good, comes the bad with this plant.
@nanm Thanks. I normally do not like the arrival of Autumn, since winter quickly follows (and I don't like winter). However, after a series of back to back extremely hot and humid days, I am looking forward to cooler weather.
