Colocasia 'Fontanesii' Black Stem Elephant Ear Bulb

Colocasia 'Fontanesii' Black Stem Elephant Ear is a striking tropical plant that adds bold elegance to any garden. Growing 3 to 6 feet tall, this beauty features large, glossy, heart-shaped leaves held aloft on sleek purple-black stems, creating a rich and mysterious appearance. Though it may occasionally produce cream to tan spathes, these flowers are typically hidden by the dramatic foliage.

Also known as Colocasia esculenta 'Fontanesii', this frost-tender perennial thrives in Zones 8-11. Its upright habit makes it ideal for large containers, pond margins, or rain gardens. Whether planted as a solitary statement piece or in mass groupings, its tropical foliage pairs beautifully with flowering companions, transforming any landscape into an exotic retreat.

Low maintenance and adaptable, Black Stem elephant ear thrives in sunny to partially shady spots with fertile, rich soil that remains consistently moist. Afternoon shade is beneficial in hotter climates to maintain its vigor. Its deer-resistant nature makes it a reliable choice for gardens prone to wildlife disturbances.

Plant the 7- to 9-inch rhizome in mid-spring once soil and air temperatures are consistently 60°F or warmer. Space bulbs 2½ feet apart and bury them 2 to 3 inches deep. In colder climates, dig up bulbs in fall and store them in a cool, dry location where temperatures stay between 45°F and 50°F, ready to replant in spring.
