Sweet Mimosa. One of the most useful tropical plants that is very cold tolerant, blooms all winter through spring with honey-fragrant flowers - canary yellow powder puffs, attracting bees and butterflies. This is a large size, multi-stem thorny shrub 15x15 ft that requires some space. It is very fast growing, can be used as a good screen plant. It will bring you joy with pretty flowers and sweet fragrance even during freeze snaps when other trees lose leaves and suffer. This one will continue blooming and stays evergreen - a real survivor! Tolerates poor soils and drought too. Provide regular water to establish quicker.
