In the garden

A member of the genus Chrysanthemum in the family Asteraceae, Chrysanthemum coccineum 'Kelway's Glorious' produces upright, multi-stemmed clumps topped by daisy-like flowers through August to October. The foliage is lobed, aromatic and mid to grey-green; the leaves are deciduous and contribute texture before the plant dies back for winter. Place the plant in full sun on a fertile, well-manured loam with a neutral to slightly acidic pH. It prefers moist but well-drained soil and a sheltered situation on a south- or west-facing aspect. Hardiness varies with group from H2 (half-hardy) up to H5 (hardy) — in other words, some selections will need winter protection while others tolerate average UK winters; the equivalent USDA range is 5–9. Use 'Kelway's Glorious' where a late-summer to autumn show is wanted, such as a sheltered herbaceous border or a sunny, protected bed. Sit it away from exposed, windy sites and keep soil consistently moist but not waterlogged. The aromatic, lobed foliage remains a recognisable feature after flowering and will be gone by winter as the plant dies back.

Care notes

Pruning and caring for Chrysanthemum coccineum 'Kelway's Glorious'

Cultivation
These are hungry plants: feed and water generously right through the growing season. Stop the growing tips in early summer to build a branching, well-furnished plant, stake before the flower weight arrives, and lift tender or exhibition kinds after flowering to overwinter the stools in a frost-free frame.
Pruning
Pinch out growing tips in late spring and early summer to encourage branching. Cut stems down to about 15cm after flowering, then lift for storage where the cultivar is not reliably hardy.
Propagation
Take basal cuttings from overwintered stools in late winter and early spring. Hardy border kinds can also be divided in spring.
Pest resistance
Aphids, leaf miner, capsid bug and earwigs all favour the soft growth; eelworm affects long-established stools.
Disease resistance
Susceptible to white rust and powdery mildew under glass or in crowded plantings, so ventilation is essential.
