propagated wisteria has yellow bottle brush flowers

Question

My seed propagated wisteria has produced yellow bottle brush type flowers. Can anyone explain what has happened? The leaves are made up of thousands of tiny oval shaped leaves. The pods came from a mauve flowering wisteria and this new plant grows quite vigorously. Please see my previous post for other details, as I’ve added this to show photo of the flower itself. I grew seven plants & they all look the same.

Answer 1

Those leaves look like some kind of mimosa, and the flowers could be in that group also. My guess is that some flying seed got into the pot you were starting your wisteria in, and grew in its place.
