Illustris Colocasia is a classic beauty. The heart-shaped, large purple-and-green leaves of Illustris are huge, and their dark highlights are stunning. This elephant ear is a lover of moist shade, but does best with a little dappled sunlight. It will tolerate boggy conditions. Provide light shade to full shade and consistently moist or boggy soil. It is a strong fast growing variety that does great in container, landscapes, ponds and patios.
