When to plant Feverfew in Cool Australia

Cool zone — applies to Hobart, Canberra, Ballarat, Orange, Armidale and similar areas. Growing elsewhere? Temperate · Subtropical · Tropical · Arid.

Sow feverfew direct from September to November, once the worst of the cool-zone frost has eased and the soil is starting to warm. Scatter the fine seed just 3 mm deep and press it in lightly, as it germinates best with a little light. Expect seedlings in 10–14 days with steady spring warmth. Thin to 30–45 cm between plants with rows around 45 cm apart, giving each bushy plant room to fill out. This hardy perennial daisy takes roughly 90–120 days to reach its froth of white, yellow-centred flowers, making it an easy, long-lived filler in gardens around Hobart, Canberra and Orange.

Growing notes

Feverfew is one of the more forgiving perennials for cool gardens, thriving in full sun to light shade and shrugging off frost once established. It prefers free-draining soil and actually flowers more freely when not overfed, so hold back on rich manures.

The main failure mode here is sowing too early into cold, wet ground, where the shallow 3 mm seed rots or germinates so patchily that weeds take the bed first. Wait until September to November when the soil has warmed, and keep the surface just moist through the 10–14 day germination. If spring is slow around Ballarat or Armidale, start in punnets on a warm sill and transplant.

Once growing, feverfew self-sows readily, so a single plant becomes a colony unless you deadhead. That is handy for cutting and drying but a nuisance in tidy beds, so cut back spent flowers before they shed. Powdery mildew can appear in humid, still autumns; space plants at the full 30–45 cm and thin crowded growth to keep air moving. Cut the whole plant back hard after its main flush and it usually rewards you with a second wave.

Common questions

When do you sow feverfew in a cool climate?

Sow direct from September to November, once frost has eased and the soil has warmed. Cold, wet ground earlier in the year causes patchy germination and rot.

Does feverfew come back every year?

Yes, it is a hardy perennial that survives cool-zone frosts and resprouts each spring. It also self-sows freely, so it often spreads on its own.

How far apart should feverfew plants be?

Space them 30–45 cm apart with rows around 45 cm. Good spacing keeps air moving and helps prevent powdery mildew in humid autumns.

Why is my feverfew getting a white powdery coating?

That is powdery mildew, common in still, humid weather. Thin crowded growth, keep plants well spaced, and cut back hard after flowering to freshen the plant.
