Add item to quote to see pricing

Oxalis triangularis is a truly mesmerizing perennial, known as the Purple Shamrock, a stellar addition to any landscape. Particularly valued for its dramatic dark purple foliage, the plant features uniquely triangular leaves that exhibit a remarkable day-night rhythm; they tenderly fold down as the sun sets, and enthusiastically greet the sun as it rises each day. Adding to its appeal, the Purple Shamrock showcases a flourish of delicate flowers, ranging from light pink to soft lavender, from late spring through summer. With a moderate stature - growing anywhere from half a foot to an entire foot tall and wide, this plant fits perfectly in various settings, including container gardens or as an understory accent. The Purple Shamrock is a resilient survivor, with modest water requirements and a preference for partial sun to shade, which when combined with its compelling day-night leaf movement, makes it a fascinating choice for both indoor and outdoor gardeners. Whether you're just starting to explore the world of gardening or are an experienced botanist seeking something visually striking and easy to maintain, Oxalis Triangularis invites you to indulge in tropical Brazilian heritage, while elevating your landscaping or indoor plantscaping experience.
