Hi there! My neighbor (in Minnesota, zone 4a) has a pretty plant in her front yard, but in one year it has filled an entire garden bed. It is about 2 feet tall and has small yellow multi-petaled flowers. Once the flowers fade, a skinny pod-like thing appears. That suggests to me it might be in the legume family? It is a rather bushy lush looking plant. Anyone know what it is? I have not seen one of these around here.
Thanks for your help!
