About Dumb cane
Dieffenbachia seguine, commonly known as Dumb Cane, is a tropical indoor plant cherished for its lush, variegated foliage. Its large, oval leaves, often displaying patterns of spots or stripes in shades of green, white, and cream, make it an attractive focal point in any living room or office. It is ideal for adding a touch of greenery and exoticism to indoor spaces.

Care tips
It requires bright, indirect light; direct sunlight can scorch its delicate leaves. Keep the potting mix consistently moist but avoid waterlogging, allowing the top layer to dry out slightly between waterings. Use a well-draining potting mix rich in organic matter. A common mistake is exposure to cold drafts or sudden temperature changes, which can lead to leaf drop.
