Pink Buttercups

Oxalis adenophylla


Oxalis are in the Wood Sorrel family, Oxalidaceae, and the roughly 500 species are native to South Africa and South America. The foliage is composed of hand-like, or ‘palmate,’ leaflets and the flowers are usually pink, white or yellow. Oxalis adenophylla, Pink Buttercups, aka Silver Shamrock, are native to the alpine areas of Argentina and Chile. The flowers are purplish pink with white throats, and the leaflets are silvery-blue and pleated.


Pink Buttercups may be planted directly in the ground or in containers. They require excellent drainage, so if you live in an area with poor-draining soil or wet winters, you may consider planting in containers instead.

To plant in the ground, choose an area with well-draining soil that receives full sun to part shade. Rock gardens are a good choice. Plant bulbs 3” deep and 3-5” apart. The end with the stringy hair roots is the bottom; if in doubt, plant the bulbs sideways. Water well.

To plant in containers, use good quality container mix that drains well. Plant bulbs 1 to 1 ½” deep and 3 to 4” apart. Water well and store the container in a cool, dry area, about 40 to 50 degrees Fahrenheit. Water very sparingly over the winter, until you see evidence of growth in the spring.


Keep the Pink Buttercups moist during the spring and summer growing season. Feed annually at the beginning of the growth season with a well-balanced fertilizer. Mulch in colder areas to protect bulbs from the winter freezing and thawing cycles.

If planted in containers, keep moist during the growing season. Feed on a regular basis, following the directions on the fertilizer label. In late summer or early fall, gradually decrease watering to allow the plant to die back and go dormant. Store the bulbs right in the container in the dry soil, and put in a cool, dry area, about 40 to 50 degrees Fahrenheit. Repot in the spring with fresh soil. Divide tubers if crowded.
