What it's good for, and what it isn't

Garden heleniums are upright, clump-forming perennials that pour out yellow, orange, copper-red and brownish-red daisies with a domed centre from midsummer into autumn, much loved by bees and butterflies. They belong in sun and in rich soil that does not dry out in summer: in dry ground they lose their lower leaves and flower poorly, so water in drought. Cultivars differ a lot: some are 60 cm and stand without support, others reach 150 cm and need staking, and the start of flowering differs by weeks between cultivars (July to August), so always check height and season. Taller ones can be cut back in early June, a good six weeks before flowering, to make them shorter and bushier, and the clumps should be divided every three to four years.

Watch out for

In drought the lower leaves turn brown and drop, leaving bare stems, and powdery mildew appears; leaf spot and rust can also occur. Tall cultivars flop in rain and wind unless staked or cut back in early summer. The centre of the clump wears out after a few years and flowering declines without division. In the hot, dry summers of Central Europe it does not look good without watering and mulch.
