Elephant ears, or colocasia, are a great way to add a tropical feel to your garden. I like to use them as an accent in a container or as a backdrop in a border with other plants. I am especially fond of the dark purple leafed variety ‘Black Magic’. The color adds both depth and a sense of mystery to the garden.
Elephant ears need consistent moisture, but at the same time thrive best in well-drained soil. Elephant ears are cold hardy to zone 9, so plant them after the last frost date in your area. If you live in a cold climate dig the bulbs up after the plant dies back in the fall and store them in sawdust or mulch over the winter.
