Oxalis (Shamrock)

Shamrocks belong to a broad genus from open spots in fresh soils in partial shade in woods in the Northern hemisphere respectively in montane and subalpine regions in rocky soils in full sun in the Southern hemisphere (the Andes in South America). They are either annuals or herbaceous perennials, whereas few species make shrublike branches. Annual and perennial species make dense floriferous carpets in early spring. Easily grown in any humus rich, slightly moist soil in partial shade to full sun respectively in any rich, very well drained, slightly rocky soil in a protected spot in full sun for subalpine members from the Southern hemisphere. Shrublike species must be grown frostfree throughout the year.
Sow the dustlike seed on top of any humus rich, well drained soil. Only slightly cover seeds and keep soil always moist from beneath. Winter hardy Oxalis species require a cooling period for several months before they germinate in late spring to early summer, thus during winter place pots outside in a protected spot. Carefully transplant the dormant rootstock to the garden as soon as leaves start to wither and plants go dormant in summer.
