The showy flowers, up to 2 (50 mm) inches long, range from pink to magenta. As shown in the photo the flowers fade from pinkish or purple to white. Mimosa dysocarpaVelvetpod Mimosa flowers, up to 20 or more in dense heads with exerted stamen. Individual heads are in synchronous bloom. Flowers bloom from May to September with fruiting soon thereafter. Mimosa dysocarpaVelvetpod Mimosa is a shrub with multiple short dense branches and stems. The stems have many spines in groups of 3 or 4. The leaves “close” when touched like "Sensitive Briar, M. roemeriana", leaves linear-lanceolate.

Genus Information: In North America there are 22 species for Mimosa. Most native Mimosa are found in Texas. Worldwide, The Plant List includes 708 accepted species names and a further 344 scientific names of infra-specific rank for the genus.
The genus Mimosa is closely related to Acacia and Albizia, the differences are its flowers which are reported to have 10 or fewer stamen per flower.

In the Southwestern United States: Arizona has 5 species of genus Mimosa, California has 0 species, Nevada has 1 species, New Mexico has 6 species, Texas has 17 species, Utah has 1 species. All data approximate and subject to revision.

Comments: Without a doubt Velvetpod Mimosa is one of the southwests beautiful plants with its spikes of purplish and pink flowers. Velvetpod Mimosa is very similar to Catclaw Mimosa, Mimosa aculeaticarpa as both species are armed with sharp prickles. Velvetpod Mimosa has larger and more showy elongated flowers.
According Lady Bird Johnson Wildflower Center the plants "are extremely drought tolerant and regular pruning encourages growth of more branches and flowers".

Importance to Wildlife and Livestock
Seeds of Velvetpod Mimosa, (Mimosa dysocarpa) are readily eaten by Gambel's and Scaled Quail and other ground dwelling birds. The leaves of this species are said to be marginal for livestock.
The dense thickets provide excellent cover value to both small rodents, quail and other ground birds.

Etymology:
The genus Mimosa is from the Greek word "mimos", an actor or mime and the suffix "osa" meaning resembling", a reference to rapidly closing leaves which appears to "mimic" conscious life.
