Luscious Purple Foliage
Foliage, flowers, and color of Oxalis Triangularis is charming! Lovely in hanging baskets or containers but may be grown in the ground in zones 8-10. Trifoliate (3-leaflets) burgundy to purple foliage resembles a shamrock and both foliage and flowers open and close in response to light. The leaves neatly fold at night and open wide to the morning light. White to blushed pink 5-petaled flowers bloom in clusters. *NOTE: Must be lifted or taken indoors in zones 3-7.

Oxalis Plant Care

*NOTE: Must be lifted or taken indoors in zones 3-7. Choose a location with dappled sunlight. May be grown as a houseplant. When planting in a container, crowd the bulbs, spacing them just an inch apart for a lush full look quickly. Needs rich, fertile soil that is well-draining. Poke the bulbs into the soil any way up is fine. Water lightly once every couple of weeks until new growth appears in approximately 6 weeks. Provide good drainage and allow the surface to dry between waterings. Plant may go dormant in fall or if it gets too hot or too dry. If plant goes dormant, stop watering to let the soil dry thoroughly. Set aside and in a few weeks new leaves should emerge. Resume watering.
