Oxalis regnellii

Commonly known as the Shamrock Plant, this South African native loves a sunny spot, indoors or out.

They are very easy to care for plants, but they do have a few cultural requirements. Shamrocks grow best when they are grown in bright light but not direct sun, relatively cool temperatures and plenty of fresh air. They should only be planted in very well drained soil. Water regularly and thoroughly while actively growing, but keep them on the dry side during winter while they are dormant. In areas with wet winters they should be grown in raised planting beds or under the eaves of the house or taken indoors and grown as houseplants.
