Euryops cultivation: Frost hardiness varies between species. Generally, a well-drained soil and a position in full sun are the main requirements of this attractive genus, otherwise the shrubs tend to grow leggy and the flowers are not as plentiful. They respond to light pruning after the flowers have faded but do not respond well to root disturbance. Propagate from seed in spring or cuttings in summer.
