Plant Inula in well-drained soil enriched with compost or manure, choosing a sunny or lightly shaded spot. Allow plenty of room – each plant can spread to about 1m (3ft) across and 2m (6.5 ft) tall. Water regularly in dry spells during the first season, and mulch in spring to retain moisture. In more exposed positions, use brushwood or bamboo canes to provide support.

Cut stems back to the base in late autumn or winter after flowering, and lift and divide clumps every few years to rejuvenate and control size.
