Geranium-leaf Aralia


Polyscias crispatum'

Polyscias crispatum or Geranium-leaf Aralia, a native of Brazil, is an evergreen shrub or small tree with a compact habit. It reaches about 12 foot in nature and is widely used as for hedges in the tropics.

Blooming Time: Flowers are small and inconspicuous and are seldom produced outside of the tropics.

Culture: Polyscias crispatum need full sun to partial shade with warm to intermediate temperatures. We grow ours under 52% shade all year long. A suitable soil mix consists of 1 part peat moss to 2 parts loam to 2 parts sand or perlite. Although the plants are tropical, in nature they should be grown on the dry side. The most common failure with Aralias is over-watering. During the growing season, the plants are fertilized every other week. During the winter months, water the plant carefully and try to avoid cool drafts.

Propagation: Polyscias crispatum is propagated by cuttings. Cuttings should be at least 8 inches long and inserted into the pot that they will be grown in. Roots develop in 3-4 weeks at 75° F.

Polyscias crispatum was featured as Plant of the Week February 15-21, 2002.
