This is a very graceful tree with a unique flat top which creates an interesting canopy effect. The light sensitive leaves close at night. It has delightful, fluffy pink summer flowers and fern like leaves. It is a fast grower, but in this region seldom grows taller than 25 feet. It enjoys high summer heat when adequate water is provided. It is hardy to USDA Zone 6, but handles colder winters better as it ages. When the flowers fade and fall off, they create a beautiful, soft, pink carpet.
Grow in full sun and well drained soil; not particular to soil type. Mimosa are border-line hardy, so place them were they may receive some protection from winter winds. They may die-back in very cold winters, though this becomes less of a problem as the tree establishes and matures. But it happens. On the other hand, there are some lovely specimens on the east side of a couple of homes up on Wasatch Blvd, so you never know...
