Background

Montauk daisy is one of the last flowers standing in the autumn garden — the clean white daisy flowers with yellow centres open just as most other perennials are winding down, carrying through until hard frost finishes the season. It forms a substantial woody-based mound that needs cutting back hard in spring; skip this and the plant becomes leggy and falls open at the centre.

Cut back to 6–8 inches in early spring before new growth starts — this is the single most important task for keeping the plant compact and floriferous. The fresh white flowers are excellent in autumn arrangements alongside dahlias, ornamental grasses, and late asters. Pairs naturally with the same seaside, full-sun conditions that suit ornamental grasses.

Seasonal tasks
summer
watchPinch tips once in early summer to encourage bushy growth and more flower stems — skip pinching if growing through a fence or other support that will hold the plant upright naturally
cutChelsea chop now — cut back by a third to keep the mound compact and stagger bloom into autumn
