Imperial Taro 'Illustris' (Colocasia antiquorum 'Illustris'): Dramatic Dark Foliage

Imperial taro 'Illustris' is a striking elephant ear with large, heart-shaped leaves that are deep purple-black with bright green veins and margins. The effect is like stained glass. Native to tropical Asia, Colocasia antiquorum 'Illustris' grows from corms and thrives in wet conditions—even standing water.

Cultivation and Uses

Full sun to partial shade (best color in sun). Rich, consistently moist to wet soil. Perfect for pond margins, bog gardens, and containers with saucers. Fertilize heavily. In zones 8-11, corms overwinter in ground with mulch; cooler zones, lift and store dry.

Design Ideas

Combine with chartreuse plants (like 'Margarita' sweet potato vine) for high contrast. The leaves hold water like cups. It's a dramatic centerpiece in tropical containers.
