Calliandra californica

Calliandra californica, the Baja fairy duster, is an evergreen, woody shrub which is native to Baja California, Mexico. In Spanish, the plant is also known vernacularly as tabardillo, zapotillo or chuparosa. The flowers, which appear in early summer, have clusters of red stamens. The shrub is usually between 0.6 and 1.8 metres in height and has bipinnate leaves. The leaves have been described as "fern-like." Leaves close at night time.
"Calliandra californica" is cold tolerant to temperatures of 22 degrees Fahrenheit, though its roots will tolerate temperatures as low as five degrees Fahrenheit. It grows best in full sun. "C. californica" is very drought tolerant, needing only 10 inches of water every year. However, additional watering will encourage "C. californica" to bloom through summer and again in the fall.
Propagation of "C. californica" is done through "acid scarification" or vegetative cutting. Seed pods from this plant look like "snow peas" and when ripe, they explode. The pods are flat and about 2 inches long. After ejecting seeds, the curled open pods remain attached to the plant for some time.
"Calliandra californica" attracts both bees and hummingbirds.
Along with many other legumes and leadworts ("Plumbago"), it is a host plant for the Marine Blue caterpillar ("Leptotes marina").
In landscaping, it is suggested that "C. californica" is used in borders or foreground plantings, as an island accent or even in containers.
