Oxalis (Shamrock)

Shamrocks, sorrels and sourgrasses are a broad genus from either open spots in fresh soils in partial shade in woods in the Northern hemisphere, or in montane and subalpine regions in rocky soils in full sun in the Southern hemisphere, especially in the Andes in South America and in South Africa. 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.

Oxalis gigantea (Giant Shamrock)

Oxalis gigantea (Giant Shamrock)

80 (150)cm, Giant Shamrock is an utmost unusual evergreen to deciduous Oxalis member with slightly woody, narrow branches, slightly succulent, glossy, mid green leaves and bright yellow flowers. It has a unique growing habit in comparison to most other Oxalis species which usually are herbaceous annuals or perennials. It is native of arid regions in western Chile. Easily grown in any rich, very well drained, rather inorganic substrate at a minimum of some 15°C throughout the year in full sun. During its summer dormancy, and when most leaves are shed, keep plants drier. Sow flat on any rich, well drained soil and keep sowings at some 20°C in a sunny spot. Do not cover seeds with soil, or add a very thin layer only. Oxalis gigantea can also be propagated from stem cuttings which are preferably taken towards the end of the dormancy period and before plants come into new growth in late summer to early autumn. IV-VIII.
