Oxalis spp.
Shamrock plant
Clover-like leaves open in the light and fold at night, often accompanied by small five-petaled flowers. These ornamental shamrocks are Oxalis rather than true clover. Green and purple forms may be available, and a natural rest period does not necessarily mean the plant has died.
