Oxalis triangularis - ‘Purple Shamrock'

Purple Shamrocks are a charming addition to any home, with strikingly large, triangular leaves that close at night and reopen with the morning sun. The leaves of the Purple Shamrock look quite similar to clover, but shockingly, they are not related. Fun fact, Purple Shamrocks are actually easier to grow as a houseplant than clover is! 

The Purple Shamrock is considered invasive in some parts of the world when it is planted in the ground, so one can imagine it isn’t difficult to care for. They prefer bright, indirect light but are tolerant of shady conditions.

While watering your shamrock, only soak the soil when the top inch of the soil is dry. Purple Shamrocks aren't picky about humidity, either making them an easy-to-grow houseplant.

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 4.5-Inch Nursery Pot.
