Pink Fairyduster, Fairyduster, Mesquitilla, Mock Mesquite
Fabaceae (Pea Family)
Synonym(s): Calliandra eriophylla var. chamaedrys, Calliandra eriophylla var. eriophylla
USDA Symbol: caer
Fairy-duster is a straggling, densely branched, deciduous shrub to 3 ft., though usually much shorter, with grayish-pubescent leaflets, flowers and pods. The petals of fairy duster are inconspicuous; it is the long, pink filaments of the stamens that make the showy display.
This little shrub is an inconspicuous part of the arid landscape most of the year, but in spring the exquisite clusters of flowers with their many long stamens form delicate, pink balls, giving the plant a fluffy pink appearance in full bloom. It belongs to a group of mostly tropical woody plants that includes acacias and mimosas.

Soil Description: Dry, gravelly soils, neutral alkaline.
Conditions Comments: Low densely branching plant with small compound leaves and 2" flowering balls, formed by the long pink filaments of 20 or more exerted stamens emerging from small clustered flowers. Seeds will typically germinate without pretreatment; however, nicking will generally hasten and unify germinatation. Seedlings are fast growing and easy to move to larger containers. It prefers dry, gravelly soils in full sun but will accept partial shade althought will flower less. Though slow-growing, fairy duster is valuable as erosion control. It is extremely drought-tolerant and somewhat resistant to browsing. Tip-prune to increase density.
BenefitUse Ornamental: Works well as an informal hedge and in medians (size is well constrained). Good choice for dry desert and rock gardens with limited space. It can tolerate some shade, but will flower most profusely in full sun. Its dense root system provides erosion control.
Use Wildlife: Calliandra eriophylla is highly palatable to deer. Its flowers attract butterflies and hummingbirds, and quail eat its seeds.
