Diamond Head Elephant Ear (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! Each heart-shaped leaf unfurls as near purple-red before taking on that near-black, gothic hue!

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. These gorgeous plants are formal and informal tropical accents and specimen plants that are sure to attract all the attention in the landscape!

Mature Elephant Ear plants reach a height of 4 to 5 feet with their leaves up to 2 feet wide. These corms can be used in growing zones 8 to 11 as perennials, and annual accents in all growing zones. Northern growers can dig Colocasia corms in the fall and store them in a cool, dark location for the winter.

Planting and Application:

Containers, planters, and in the ground, you won't go wrong with these fantastic focal points!

This plant performs best along the edge of a pool or submerged in a water feature. Any higher moisture location along streams, Rain Gardens, and that boggy area around the HVAC unit that can use some tropical flair. The dramatic hue and gothic effect of this accent plant will look great in any garden!

#ProPlantTips for Care:

Elephant Ear corms can be picky about moisture, if left in dry conditions, the 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! Provide regular moisture and a well-drained organic location for best results. Gardeners in zones 3-7 may overwinter the corms indoors covered by peat moss. Dig up the corms after the leaves have been dried by frost. Store them in dry peat moss or wood shavings. Place in a warm, dark and dry place with a temperature no higher than 50-60°F.

  • Full Sun & Partial Shade
  • Moist Well-Drained Soil
  • Regular Fertility
  • Dig Corms in Fall & Store
  • Low-Maintenance Annual in Cold Climates
