Several species are too tender to grow outdoors – Chincherinchee (O. thyrsoides) is grown as a pot plant and sold as a cut flower. There are three species which are hardy, however, and two of them are native to Britain. The star-shapedappear in spring, and are always a combination of white and green.
VARIETIES: O. nutans is the best one to buy – about a dozen pendent blooms are borne on each– 1 in. bells with pale green backs. O. umbellatum grows to the same height (1 ft) but it has a different habit – the flat white stars face upwards and open during the day. Plant it with caution – it can easily become a weed. O. balansae (6 in.) is a dwarf for the rockery – the white petals are striped with green.
SITE AND SOIL: Any well-drained soil will do – thrives in sun or partial shade.
PLANT DETAILS: Planting time October. Planting depth 2 in.
