The garden crotons should not be confused with Croton

Croton (genus)

Croton is an extensive flowering plant genus in the spurge family, Euphorbiaceae, established by Carl Linnaeus in 1737. The plants of this genus were described and introduced to Europeans by Georg Eberhard Rumphius. The common names for this genus are rushfoil and croton, but the latter also...

, a cosmopolitan genus also in the Euphorbiaceae, containing more than 700 species of herbs, shrubs and trees.

Cultivation

In tropical climates, crotons make attractive hedges and potted patio specimens, valued for their striking foliage. They only survive outdoors where temperatures do not normally drop below 10° to 13°C in winter; colder temperatures can cause leaf loss. In colder climates, the plants are grown in greenhouses or as house plants. The cultivated garden crotons are usually smaller than the wild plant, rarely over 1.8 m tall, and come in a wide diversity of leaf shapes and colours. They are sometimes grouped under the name Codiaeum variegatum var. pictum (Lodd.) Müll. Arg., though this is not botanically distinct from the species and usually treated as a synonym of it.
There are several hundred cultivar

s, selected and bred for their foliage. Depending on the cultivar, the leaves may be ovate to linear, entire to deeply lobed or crinkled, and variegated with green, white, purple, orange, yellow, red or pink. The colour patterns may follow the veins, the margins or be in blotches on the leaf. Popular cultivars include 'Spirale' which has spirally-twisted red and green leaves; 'Andreanum' which has broadly oval yellow leaves with gold veins and margins; 'Majesticum' which has pendulous branches, with linear leaves up to 25 cm long with midrib veins yellow maturing to red; and 'Aureo-maculatum' which has leaves spotted with yellow.
