Background

Evening-scented stock — once known as the melancholy gillyflower — is grown for one thing above all: scent. By day the plants are unremarkable, with thin grey-green leaves and small, half-closed lilac flowers that look almost wilted. At dusk the flowers open fully and release a sweet, clove-and-honey perfume strong enough to carry across a whole garden, drawing in night-flying moths.

It is a fast, easy hardy annual. Direct sow where you want it — near a path, doorway, or seating area where the evening fragrance can be enjoyed — since it resents transplanting. Scatter seed every few weeks from early spring for a long run of scented evenings, and sow generously: the daytime appearance is modest, so plant it in drifts and let neighbouring flowers carry the daytime show.

Seasonal tasks
spring
sowDirect sow seeds on the soil surface; they need light to germinate.
sowSow a second round outdoors after last frost for staggered bloom.
watchCheck rosettes for flea beetle damage as growth resumes.
summer
cutDeadhead spent flower clusters before seed pods form to control self-seeding.
cutCut back flowering stems after bloom to encourage tidy rosettes.
watchInspect leaves for white rust and powdery mildew in humid weather.
fall
watchPull volunteer seedlings to keep the plant from spreading into wild areas.
Common problems

White Rust

Symptoms

Raised white to cream-colored pustules on leaf undersides, with yellow blotches on upper surfaces. Infected tissue may swell or distort.

Treatment

Remove and destroy infected leaves. Improve air circulation and avoid overhead watering. Rotate brassicas and avoid planting in previously infected soil.

Powdery mildew

Symptoms

White or grey powdery coating on leaves — usually starting on older growth in humid conditions or when nights cool.

Treatment

Improve air circulation by thinning plants. Apply neem oil or potassium bicarbonate spray at first sign. Avoid overhead watering.

Downy mildew

Symptoms

Yellowing on top of leaves with grey-purple fuzz underneath. Spreads rapidly in humid conditions.

Treatment

Remove affected leaves. Improve air circulation. Avoid overhead watering. Copper spray as preventive.

Clubroot

Symptoms

Swollen, distorted roots; wilting in midday heat; stunted growth and yellowing foliage. Plants recover poorly even with watering.

Treatment

Remove and destroy infected plants with roots. Raise soil pH toward 7.2 with lime. Improve drainage and rotate out of brassicas for several years.

Pests

Flea Beetle

Alticini →
Symptoms

Small round shot-holes scattered across leaves; tiny dark beetles that jump when disturbed. Heavy feeding stunts young plants.

Treatment

Use floating row covers on seedlings. Remove crop debris and weeds that harbor beetles. Apply kaolin clay or spinosad if damage is severe.
