Shark Fin Dracaena masoniana

The whale fin dracaena or whale fin snake plant is a rhizomatous herbaceous perennial from tropical Central Africa. It is a member of the asparagus family (Asparagaceae). The species epithet honors Maurice Mason, a British grower of succulents who popularized this species, which was known Sansevieria 'Mason's Congo' before it was given a formal scientific name. This plant had been classified in the genus Sansevieria, but after genetic studies, it was determined that it belonged to the genus Dracaena.

This plant prefers bright, indirect light, and is tolerant of low light conditions. The planting medium should include a mix of perlite, coarse sand, and organic matter to encourage adequate drainage and aeration. It is very drought tolerant, and it is best to allow the growing medium to dry out between watering. Most importantly, avoid overwatering. The whale fin snake plant thrives in temperatures between 65 to 85 degrees Fahrenheit and humidity levels of at least 50%. Avoid cold drafts and temperatures below 55 degrees Fahrenheit. Repot when the plant is pot-bound or when the roots grow out of the drainage holes of the container. This plant can be propagated by division or leaf cuttings.

The Whale Fin Snake Plant has an erect habit and grows 3 to 5 feet tall and 1 to 2 feet wide. It is a semi-succulent plant with paddle-shaped leaves that measure up to 3 to 4 feet long and 8 to 10 inches wide leaves. The leaves are dark green, thick, stiff, waxy, and mottled with light green spots. Just below the soil there is a purple banded sheath. The leaf resembles the fin of a whale or shark. The plant has white flower clusters that grow from the center of the plant and appear during the summer.

This plant acts as an air filter and can remove toxins from the air of your home. It requires very little maintenance and is the perfect plant for beginners. Be aware that the leaves and sap are toxic if ingested. Keep the plant out of the reach of pets and children.

Insects, Diseases, and Other Plant Problems:  Monitor for spider mites, scale, mealybugs, thrips, and aphids. Black spot and root rot can occur from overwatering. Direct sunlight can scorch the leaves.
