Oxalis, commonly known as the Shamrock Plant, is a charming houseplant that brings Irish luck indoors with its distinctive purple triangular leaves. Native to South America, this delightful plant has become synonymous with good fortune and is especially popular around St. Patrick's Day. The leaves perform a fascinating daily dance, folding up at night and opening again with the morning light. With proper bright light, Oxalis produces delicate pink star-shaped flowers that complement its vibrant purple foliage perfectly.
