In the garden
Galtonia candicans grows from a bulb to form upright stems around 1–1.2 metres tall bearing multiple white flower spikes in July to August; the blooms are scented and are traditionally used for cutting. Its origins lie in the moist grasslands of South Africa and Lesotho, which explains its preference for soil that remains moist without becoming waterlogged. Place Galtonia candicans in full sun or partial shade on fertile, well-drained soil that retains some moisture. The species is rated H4 (average) for hardiness, so it will survive typical UK winters in most sheltered to open gardens provided drainage is good. In containers choose a free-draining potting mix and avoid prolonged waterlogging. Tall stems make it a useful structural plant at the back of a border or in a mixed container where height is needed in midsummer. Because the flowers are scented and borne on long stems it performs well as a summer cut flower; stems can be picked for arrangements during the main July to August display.
