This easy-to-grow charmer works both indoors and out. Oxalis bears colorful, cloverlike leaves that close up at night. They appear in a range of colors from silver to purple -- and several are variegated with other colors. The cup-shape blooms are also attractive and appear in shades of yellow, pink, and white.
Indoors, some oxalis varieties will bloom all year if given enough light. Outdoors, treat them as delightful summer annuals or choose perennial selections that are hardy for your area. Most oxalis selections do best in part to full shade and well-drained soil. Be sure not to overwater.
