DESCRIPTION: These palms are found from Mexico to South America. They can be grown in doors as houseplants or hothouse if they have a minimum winter temperature of 60 degrees. In parts of California and Florida that are free of frost, they can be grown outside in a shaded area. These Palms have thin stems and large, elegant leaves. C. graminifolia is very pretty and is suitable for cultivating in pots. C. Pringlei is a dwarf Palm that is great for pots and foreground planting outdoors in frost-free regions. C. costaricana has clumps of bamboo-like stems, 12-15 feet tall, and is one of the hardiest.
POTTING: These plants can grow in well-drained pots filled with equal parts of loam and peat with a generous amount of sand added. During the summer they need a moist, tropical atmosphere and plenty of shade.
PROPAGATION: To reproduce this plant, you need to soak the seeds in water for a day or two before sowing in a hothouse in the spring. Some kinds can be increased by division.
