What a way to make a statement on your patio, deck or any sunny spot in your yard!
Elephant Ears (Colocasia esculenta 'Diamond Head') is a stunning new addition to the variety of Elephant Ears. Their broad, blue-black leaves have a smooth surface and a gleaming sheen that reflects the light.
For the best color, grow it in full sun. Mature plants reach a height of 4 to 5 feet with their leaves up to 2 feet wide.
Diamond Head is named after the volcanic cone on the Hawaiian Island of Oahu because both the cone and the plant are black and lustrous. This plant performs best along the edge of a pool or submerged in a water feature.
This plant can be picky in where you place it. If left in dry conditions, its leaf edges will burn. In the shade, it will lose its luster and appear dark green instead of purple or black. The Purple-black color is what makes this plant so special!
Gardeners in zones 3-7 may overwinter the bulbs indoors covered by peat moss. Dig up the bulbs after the leaves have been dried by frost.
Add this stunning plant to your yard from Nature Hills and be ready to have your neighbors stop to take a look!
