I love my Mimosa, but boy are the flowers messy!! Don't put it near a BBQ/Eating/Socializing area, like I did!!
I love the flowers, I love the wonderful fragrance, especially at night. I love that it attracts hummingbirds and the butterflies. I love it's form and shape. Again, it does not provide heavy shade. I would say moderate shade, with it's fern like leaves. If I had it to do over again, i would have planted the Mimosa in the lawn, and my Pink Trumpet tree out by the BBQ pit.
