Description

This genus is the largest genus in the Euphorbiaceae (spurge) family. However, the genus does not have the latex that is usually found in spurges. There are 431 species in this genus some of which are native to the US. Its members can be annuals, perennials, houseplants, shrubs, small trees, or even ground covers. They are found all over the world but mostly in tropical and subtropical areas. The genus name comes from the Greek word for "nettle" as the leaves resemble those of nettles. 

They are often grown as ornamentals for their foliage and they have very showy pendulous inflorescences.  Generally, they require low to medium maintenance with similar requirements for watering.

They are best used as an accent plant as the very showy leaves make them stand out. Plant too many and they can overpower your other plantings. Those with less showy leaves can also be used as a hedge along a border or near a patio or pool.  Some plants also work well in containers or having their inflorescence dangle from a hanging basket. In cooler climates, they are grown as a houseplant.

Insects, Diseases, and Other Plant Problems:  No serious problems.

    Leaf Description:
    The leaves of this genus come in all sizes, from just over 1inch to 8 inches long. The same is true of the shape. The leaves can be heart shaped, elliptical to lanceolate, oblong and even rhomboidal. But no matter the size or shape they are all simple and carried alternately with a rough, nettle-like surface. Some have stipules; some have crenated or serrated edges; some have palmate venation and others pennate (arranged on each side of the midvein similarly to the barbs of a feather). The one we use in the garden frequently have leaves that are mottled in combinations of green, purple, yellow, orange, pink or white, but usually the leaves are green - light, mid or dark. Most species have leaves that turn reddish brown in the autumn, hence the common name 'Copperleaf'.
