About

Chrysanthemum coccineum 'Jubilee Gem' is a perennial Painted Daisy notable for its late-summer to autumn flowering from August to October. It forms an upright, well-branched clump with lobed, aromatic, mid to grey-green leaves that are deciduous. Plant in full sun on fertile, well-manured loam that is neutral to slightly acid and kept moist but well drained. A south- or west-facing, sheltered spot suits it best and hardiness ranges from half-hardy to fully hardy depending on the group (H2–H5).

In the garden

Chrysanthemum coccineum 'Jubilee Gem' belongs to the Asteraceae and is native to Europe. The cultivar offers a reliable late-season presence in the border, producing its display between August and October. Leaves are lobed and aromatic and drop back after the season, making it a plant that contributes scent as well as bloom time to the garden. Place it in full sun on a fertile, well-manured loam, with neutral to slightly acid pH and soil that stays moist yet drains freely; a south- or west-facing, sheltered position reduces exposure to drying winds. Hardiness is given as H2–H5 depending on the group, which ranges from half-hardy to hardy in UK terms; in hotter-winter climates it corresponds to USDA zones 5–9. Use Chrysanthemum coccineum 'Jubilee Gem' towards the front or middle of mixed borders, in cottage-style plantings or rock gardens where its late flowers extend the season. The aromatic, lobed foliage provides a sensory contrast when handled, and the cultivar's August–October flowering helps bridge high summer into early autumn colour.

Care notes

Pruning and caring for Chrysanthemum coccineum 'Jubilee Gem'

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.
