Eggers’ Woodsorrel: A Rare Caribbean Native Worth Knowing
Meet Eggers’ woodsorrel (Oxalis eggersii), a charming little perennial that calls Puerto Rico home. This delicate forb might not be the showiest plant in your garden, but it carries the special distinction of being a true Caribbean endemic—meaning you won’t find it growing wild anywhere else in the world.
What Makes Eggers’ Woodsorrel Special?
As a member of the wood sorrel family, Eggers’ woodsorrel shares the characteristic clover-like leaves and small, cheerful flowers that make Oxalis species so recognizable. This perennial forb grows as a low, herbaceous plant without any woody stems, making it perfect for ground-level garden interest.
What sets this species apart is its incredibly limited natural range. Oxalis eggersii is native exclusively to Puerto Rico, where it has evolved to thrive in the island’s unique tropical conditions.
