- Description
-
Purple Shamrock Plant is a rhizomatous herbaceous ornamental garden or houseplant in the wood sorrel family that is native to South America. The trifoliate leaves resemble a shamrock and can be green to variegated to deep maroon in color. The leaves close up at night or when disturbed. The white to pink 5-petaled flowers bloom in clusters in spring to summer on stems held above the plant and also close at night.
In most of NC, it will need to be grown as a houseplant. Use a loamy potting mix with good drainage and allow the surface to dry between waterings. Place in full sun to partial shade. The plant may go dormant for a while in fall or if it gets too hot or too dry. Cut back on watering and wait for new growth to appear.
