Family: Araceae

Originally from tropical America, these deciduous perennials have tuberous rhizomes and large, spear-shaped or ovate leaves, attractively patterned in red, pink, white and green. They flourish in tropical areas where they hybridize amongst themselves to produce a myriad of different leaf colourings. The bloom resembles that of an arum lily but is much smaller. Caladiums are grown for their handsome foliage, not their flowers.

Species

Most fancy-leaved caladiums are hybrids grouped under C. x bicolor. Heights vary from about 25 cm to 45 cm (10-18 in).

Cultivation

Caladiums can only be grown permanently in the garden in tropical or subtropical climates. They need shade. Elsewhere grow as summer bedding plants in shade, or as pot plants in a warm greenhouse or conservatory. They also make good houseplants. Grow them in a soilless potting compost and provide high humidity and shade from direct sun, although good light is recommended. The tubers are potted in spring and started into growth. Water plants well in summer but gradually withhold water in autumn until the compost dries out. The tubers are dormant over winter, when they should be kept warm and barely moist.
