It grows between 3.5 and 10 feet tall and produces pink flowers. This plant is considered a weed that can grow invasively in moist soils.[1]
Habitat and ecology
This species grows as a small to medium-sized shrub that is localized on limestone soil that can range from 2200 feet to 4000 feet above sea level in the desert. This plant is deciduous and has a very high heat tolerance, allowing it to grow in very hot deserts. This plant species was a contained species that escaped and became invasive in the Florida, Texas and Mexico regions. These plants live in soil with high alkalinity.[2]

Leaflets can range from 9 mm to 12 mm and be 1.5 mm wide at its widest point. Each leaf has about 12- 25 leaflets. Flowers are globe like clusters of thin petals. They contain stamens that are double the number of petals or equal which are often twice the lengths of the corolla. Anthers are small and the ovary is sessile.
Flowers and fruit
Flowers of Mimosa turneri, are produced in globe-like clusters of pink flowers. They are round in shape and are compiled of thin, long pink fuzzy petals that protrude from the center of the flower. The flowers can range from 1.5 cm – 2.5 cm long. These flowers bloom during spring summer and fall.
The fruits produced by this plant are oblong or linear and are known as legumes or pods. Fruits contain ovate or flat seeds which are separated into 2 valves.
