Of Mimosa tree (they are also called, "silk trees"), Steve Nix writes, "This fast-growing, deciduous tree has a low branching, open, spreading habit and delicate, lacy, almost fern-like foliage. Fragrant, silky, pink puffy pompom blooms, two inches in diameter, appear from late April to early July creating a spectacular sight." There's certainly enough positive there to catch one's attention! But as About's Forestry Guide relates in this article on silk trees
, you'll have to weigh Mimosa trees' drawbacks against their positives before planting them.
