About

Chrysanthemum maximum 'Phyllis Smith' is a perennial in the Asteraceae that bears white, daisy‑like flowers with yellow centres from August to October. Plants form a well‑branched, upright mound with lobed, aromatic, mid to grey‑green leaves that are deciduous. It prefers full sun on fertile, well‑manured loam that stays moist but is well drained in a sheltered, south- or west‑facing spot.

In the garden

Chrysanthemum maximum 'Phyllis Smith' is a garden cultivar of the max chrysanthemum group, a species with origins in parts of south‑western Europe including France and Spain. The cultivar carries the species' characteristic white ray florets surrounding yellow disc florets and provides late‑summer into autumn flowering, reliably producing bloom from August to October. Give the plant a sunny, sheltered position on fertile, well‑manured loam with a neutral to slightly acid pH; soil should remain moist but free‑draining. A south or west aspect reduces late‑season wind exposure, and the plant performs across a range of cold‑tolerance from H2 to H5 (half‑hardy to hardy) — this broadly corresponds to USDA zones 5–9. Avoid waterlogged ground and provide routine organic feed to maintain vigour in heavy flower years. In UK gardens it suits mixed borders where autumn colour is required and can be used in grouped plantings to create a late display. The leaves are lobed and aromatic; the scent released when foliage is brushed makes this cultivar particularly suitable beside paths or near seating where the foliage can be appreciated.

Care notes

Pruning and caring for Chrysanthemum maximum 'Phyllis Smith'

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.
