Silver Shamrock, Chilean Oxalis, Pink Carpet Oxalis, Pink Buttercups, Pink Sauerklee, Sandoxalis, Sauer Klee


Native to Chile and Argentina, Oxalis adelophylla (Silver Shamrock) is a bulbous perennial forming a dense clump of finely incised gray-green leaves composed of several heart-shaped leaflets. In late spring to early summer, open-faced, white flowers, 1 in. across, flushed with purple toward their petal tips and adorned with lilac veins, appear above the handsome, clover-like foliage. Very cold hardy, Silver Shamrock also does well in mild climates as long as the soil is kept moist but well-drained. Its considerable ornamental appeal makes it a first rate plant for rock gardens, borders and containers.

  • Recipient of the prestigious Award of Garden Merit of the Royal Horticultural Society
  • Grows up to 3-4 in. tall (7-10 cm) and 4-6 in wide (10-15 cm). In optimum growing conditions, this little plant with its peculiarly shaped tubers will have no trouble naturalizing.
  • Easily grown in moderately fertile, humus-rich, well-drained soils in full sun to part shade .
  • Undemanding and virtually pest and disease free, Silver Shamrock is a welcomed addition to beds and borders, rock gardens or containers.
  • Deer and rabbit resistant.
  • Propagate by seed, sown with moderate heat in late winter or early spring
