Genus Colocasia (Taro, Elephant's ear)

This little elephant ear has velvety dark leaves with prominent green veins and a large silvery central blotch. It reaches about 2 feet high.

A large, showy, marginal aquatic plant with heart-shaped, dark green leaves, taro can reach 5 feet tall and is often grown as a summer annual. Use it in a container or near water.

‘Black Beauty’ is my new favorite elephant’s ear. A mutation of ‘Illustris’, ‘Black Beauty’ is grown for its 2-foot-long, 1-foot-wide, dark purple leaves with green stems and green veins. Once established in my garden, this plant held onto its leaves through the heat and drought of summer in full sun, which is unusual for the dark-foliage forms of elephant’s ears: They tend to look less than lovely when temperatures rise above 90°F.

Rising to about 36 inches, the elephant ear's deep-purple stalks suspend luxurious leaves of the same color. When the leaves’ undersides are dusted with chalky-looking bloom, they have an intriguing, almost gray look. This plant does well in a bog or even in the margins of a water garden, as well as in average garden soil.

'Coffee Cups' is an unusual and relatively recent introduction. It has nearly black stems and  cup-shaped leaves. 'Coffee Cups' is a vigorous grower, and, with a height of 6 feet, it's a good choice for the back part of a border. -Andy Cabe, Regional Picks: Southeast, Fine Gardening issue #120

When breeder John Cho combined a black Colocasia and a glossy Colocasia, he created something shiny and new: ‘Diamond Head’. It is named after the volcanic cone on the Hawaiian island of Oahu, which makes sense because both the cone and plant are black and lustrous. The plant’s leaves reach at least 16 inches long and 1 foot wide. ‘Diamond Head’ performs best along the edge of a pond or submerged in a water feature. If left in dry conditions, its leaf edges burn. In shade, it loses luster and appears dark green instead of purple or black. That purple-black color is what makes ‘Diamond Head’ so special, so if the light conditions in your garden don’t suit it, you might want to choose another cultivar. -Adrienne Roethling, Elephant's Ears, Fine Gardening issue #148, page 60

Bright green leaves add light and impact any place 'Elena' sets its roots.

This chic, black-stemmed elephant’s ear packs looks great in containers, beds, and borders. It also makes a wild addition to floral arrangements.

A demure egg-shell finish and a dark purple underpinning make the foliage of 'Heart of the Jungle' special.

The foliage of ‘Hilo Bay’ looks almost like crinkled taffeta hanging off black stems. Planted en masse, this selection makes an elegant yet whimsical statement.

The heart-shaped leaves of 'Illustris' are huge, and their dark highlights are stunning. This elephant ear is a lover of moist shade, but does best with a little dappled sunlight. It will tolerate boggy conditions. -Julia Jones, Fine Gardening issue #120

You must grow this plant—if only to be able to tell everyone that you have a mojito waiting for them in the garden. Its green leaves are set off by dark flecks and purple stems. The speckled patterns, splotches, and streaks vary from leaf to leaf, so no two ever look quite the same. ‘Mojito’ makes a thrilling addition to perennial beds, where its exotic form and color will add more surprise and interest than any other shrub or perennial you might have considered putting in its place. -Adrienne Roethling, Elephant's Ears, Fine Gardening issue #148, page 58

Kitchen garden rhubarb doesn't hold a candle to 'Rhubarb' elephant's ear, at least not in an ornamental sense.

This purple-and-cream-streaked elephant's ear makes a splash in any combination imaginable.
