The standard size Callliandra haematocephala displays its name derivation from Greek Calli meaning beautiful and andros meaning male with stamens, the male parts of the flower, most visible. This red bloom stands out against the evergreen leaves as shown here.

The Powderpuff bush adds color to a landscape as shown here with either red or pink blooms depending on the variety in the fall to winter and young evergreen leaves of coppery bronze and dark green close up at night. The blooms produce a three- to six-inch brown pod at maturity and contain several seeds.

The Powderpuff bud resembles a raspberry shown here that when it is open shoots out tendril-like appendages. This dwarf variety 'Nana' bush remains under 6 foot at is maximum height and blooms for a longer period of time than the full-sized variety, providing more dense color in the landscape with more blooms.

The dwarf Powderpuff 'Nana' bloom shown here with its long appendages pronounces a free form bloom on stems of a plant that can be trimmed for a specimen or hedge, planted in a large pot for a patio plant or espaliered against a wall or fence as is the case with this plant currently in bloom along a fence in a bed bordering a driveway.
Powderpuff particulars
Red powderpuff, Calliandra haematocephala, sometimes called pink powderpuff is a fall- to winter-blooming shrub or small tree that is root-hardy in the Victoria area and lends a pop of color to winter landscapes while providing food for butterflies, other pollinators and late hummingbirds when little else is blooming.
Derivation
The scientific name is from the Greek Kali (Calli) meaning beautiful and andros, meaning male, as the most visible parts of the flowers are the stamens, the male parts of any flower combined with haemato meaning blood and cephala meaning head.
The species is native to Bolivia and has very recently been moved from the bean family to the mimosa family although older references still call them beans.
Uses in landscape, home
This versatile plant may be trimmed into tree form and will grow to 15 feet tall and 10 to 15 feet wide, trimmed into a 5-6 foot tall shrub for use as a specimen or a hedge, planted in a large pot as a patio plant, espaliered against a wall or fence, used as a house plant for a well lighted area or even used to create a blooming Bonsai.
It will stay evergreen down to about 29 degrees and die to the ground when the temperatures hit mid- to low-20s but will come back from the roots and grow to at least 6 feet tall before the next winter. There is also a dwarf variety available that will stay under 6 feet at its maximum height and blooms for a longer period than the full-sized variety.
Powderpuff is an apt description for the fragrant red, pink or white, 2-3 inch in diameter flowers produced on new wood mostly during the fall to winter with scattered blooms during spring and summer.
Before they open the flower buds resemble raspberries. The feathery evergreen leaves which are a coppery bronze when young and mature to rich, dark green close up at night, to the delight of children, and provide a larval food for the Cassius blue butterfly and probably other species, too. The flowers produce a bean-like pod three to 6 inches long which is brown at maturity and contains several seeds.
Easy care for this tough plant
Red powderpuff is an adaptable species.
It prefers well-drained clay, sand or loam soils with a slightly alkaline pH.
It grows well and flowers in full sun to partial shade and, while they bloom best with average water, they are quite drought tolerant. These plants do not like soggy soil so you may need to amend your soil or build a raised bed if you wish to plant them in a low spot.
This plant loves our heat and humidity and indoor plants should have their pots set in a tray of wet sand or gravel in order to keep the humidity around the plant high.
Fertilization should use a complete balanced fertilizer applied in spring or summer, but no later than late summer so tender new growth during the colder seasons is not encouraged. Container plants may be fertilized with a half strength balanced liquid plant food every two to three weeks during the growing period.
Pruning will, of course, be dependent upon what form you wish your plants to have. Pruning or pinching the growing tips will make for a bushier plant with more flowers, while removing low branches will give a more tree-like plant.
Left to itself the branches will be long and arching and form a symmetrical, rounded and smooth crown but this plant is easy to prune into almost any shape you desire including bonsaied or espaliered.
Calliandra is highly disease-resistant with no major insect pests although it is sometimes affected by caterpillars, including those of desirable butterflies, mealy bugs, spider mites or aphids.
Easy to propagate from seed or cutting
These plants are so beautiful you may want more and luckily they are easy to start from seeds or cuttings. Seeds should have hot water poured over them and then be soaked for 24-48 hours before planting in 70-75 degree soil where they will germinate in 1-3 weeks.
Cuttings should be taken in spring from the tips of the stems and rooted in moist soil after being dipped in rooting hormone.
If you are looking for something different and colorful for your winter landscape, protected patio or house, consider getting a red or pink powderpuff – or three. They are easy to grow as they are pleasing to the eye.
