The striking green and yellow variegation would definitely light up any room you put it in. The broad and upright leaves resemble a whales fin hence the name. Can also be called Shark's Fin Snake plant. It is an easy-care plant that thrives in bright, indirect light and is drought tolerant. This rare plant is a colorful, but hard-to-kill, houseplant that’s ideal for the busy gardener.
How to care for Variegated Whale Fin Snake Plant
Light. Bright, indirect light is best, and it tolerates low light. Direct sun can scorch the leaves.
Water. It is very drought tolerant. Let the mix dry out between waterings, and above all avoid overwatering.
Soil and feeding. Use a mix with perlite, coarse sand and organic matter so it drains and breathes. Repot when roots fill the pot or grow out the drainage holes.
Size. Grows to about 2 ft in a pot. Whale fin can reach 3–5 ft, with leaves up to 4 ft long and 10 in wide.
Problems to watch. Watch for spider mites, scale, mealybugs, thrips and aphids; treat with Insecticidal Soap. Overwatering causes black spot and root rot.
Good to know. It thrives at 65–85°F; protect it below 55°F. Leaves and sap are toxic if eaten by people, cats or dogs, and the sap can irritate skin.
