All ivies belong to the genus Hedera. These climbing vines cling to upright surfaces by roots that sprout from their stems and work into any available crevice. The vines can be trained to cover forms shaped of wire stuffed with sphagnum moss. They look great growing over the edges of containers.
English ivy (Hedera helix) has 2 to 4-inch (5-10 cm) long three or five-lobed dark green leaves, and there are varieties that exhibit some of the oddest-shaped foliage known. In color they combine green with white, cream, yellow or pink. Some popular varieties are "Golden Colibri", with green-and-white leaves; "Buttercup", whose leaves are yellow; "Manda's Crested", whose star-shaped leaves have wavy-edged lobes; and "Caenwoodiana", a particularly durable type whose dark green leaves are accented by prominent ivory-white veins. All grow well in water.
Ivies like four or more hours a day of direct sunlight, but will grow fairly well in bright indirect light, such as that reflected from light walls. Keep the soil barely moist.
Repot when containers become crowded. Cuttings will root easily. Use a good potting soil and feed well. Watch for spider mites, mealybugs, and white flies.
