History

Illustrated historical scene for Whale Fin Snake Plant

Sansevieria masoniana, commonly called whale fin or shark fin sansevieria, is a distinctive large-leaved succulent in the asparagus family (Asparagaceae) native to the Democratic Republic of Congo in central Africa. Lebanese-American sansevieria specialist B. Juan Chahinian formally described the species in 2000, honoring Maurice Mason, the British plantsman who introduced the species from African exploration. Following the 2018 phylogenetic revision of Sansevieria by Takawira-Nyenya, Mucina, and colleagues, the entire genus Sansevieria was subsumed into the older-named genus Dracaena, making the species formally Dracaena masoniana, though horticultural trade retains Sansevieria.

The plant produces enormous single paddle-shaped upright leaves 25-35 cm wide and 60-120 cm tall (rarely to 1.8 meters), pale green marked with distinctive darker green transverse bands and a maroon-red leaf margin. Rather than forming rosettes, single-leaf offsets slowly emerge from the rhizome. A highly sought collector plant since the mid-2010s.

Toxic to pets. Now reclassified by some botanists as Dracaena masoniana. A classic botanical curiosity that surged to mainstream popularity in the 2018-2022 American houseplant boom, with single-leaf specimens defining minimalist modern interiors.
