Oxalis Triangularis ‘Purple Shamrock”

Named because it isn’t actually a Clover, the family of proper Shamrocks, the purple variety of Oxalis Triangularis is much more striking with its large, triangular leaves that close at night and reopen with the morning sun. As this plant is considered invasive in some parts of the world, one can imagine it isn’t difficult to care for. Preferring bright indirect light but tolerant of shady conditions and watering when the top inch of soil is dry, it also isn’t picky about humidity making it a great indoor to plant. Use this plant to match a particular color story in your home, or to stand out among the green in the rest of your collection! Available in 4-Inch Nursery Pot.
