'Diamond Head' 'Diamond Head' elephant's ear (Colocasia esculenta 'Diamond Head') Genus:  Colocasia 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 Noteworthy Characteristics:  Dark foliage for moist or wet spaces Care:  Gardeners in cool hardiness zones may overwinter plant’s tubers indoors covered by peat moss during winter, after the leaves have been desiccated by frost. Propagation:  Plant tubers when soil is consistently around 70°F. Offspring shoots can be transplanted.
