Mimosa Tree was introduced into the U.S. from the Orient. Zones 6 - 10. These are considered a weed tree here in Georgia, because of their prolific re-seeding. I have them growing everywhere on my property. Some have even come up in the cracks of the driveway. Few nurseries in this area will sell them because of this property, but they are definitely a Southern standard. They are a favorite of hummingbirds and butterflies.
The trees can grow to 40 feet and are graceful with their arching branches and fern like leaves. It is often the Mimosa tree that can be seen in the landscaping over the curved bridges so often depicted in Oriental paintings and carvings.
Flowering begins in Summer, and the tree may re-bloom at intervals. The flowers are like puffs of silk, hence the nickname "silk tree". The flowers are delicately fragranced and in the balminess of the humid southern afternoons, the air is filled with the aroma. Mimosa blooms are multi-colored, but appear pink at a distance.
Mimosa trees do best in high summer heat. They will grow in adverse conditions such as constant wind, salt spray, and alkaline soil. They can take drought but will grow slower and look yellow.
