A seed worth growing
A fully double white feverfew.
Tetra White crowds its crown with fully double 3/4–1" blooms, pure white with centers that range from citrus yellow to lime, so each plant gives plenty of stems to cut.
Feverfew may overwinter in Zones 5–9 but tends to live only a few years there.
Flowers about 100–110 days from sowing, on plants 28–36" tall. Open-pollinated.

Know before you sow
Growing times vary with weather, soil and local conditions.
Light helps it sprout; 10–14 days at 70°F.
3–4 weeks before frost, wintered over or under a tunnel.
Full sun, 8–12" apart.
Nearly full open for drying.
About 10–14 days at 70°F (21°C).
The best method. Sow 5–7 weeks before planting out, in spring or fall. Press the seed onto the mix without covering it, since it needs light, and water from below or with a fine mist so it is not buried. Pot up into cell packs or 3–4" pots 2–4 weeks after sowing and harden off before planting out.
Plants set out 3–4 weeks before the first fall frost and wintered over, outdoors or in a high tunnel, bloom earlier the next year with longer stems; under a tunnel stems can reach about 48".
For the best stems, grow spring plantings as annuals. Early transplants into a high tunnel (once it stays above freezing inside) give long stems and heavy bloom; row cover protects early field plantings in cold snaps.
As soon as the soil can be worked. Press seed in without covering, keep the surface moist until it sprouts, and thin at the first true leaves.
Full sun. Feverfew is a long-day plant: it flowers mainly in the longest days of the year, and on shorter stems when days are short.
8–12".
A tender, short-lived perennial in Zones 5–9; spring plantings perform best treated as annuals.
For fresh use, cut when about three-quarters of the cluster is open; for drying, wait until it is nearly all open.
Light, moist, fertile soil that drains well, ideally pH 6.0–7.2.
A productive cut and dried filler; also for beds, borders and containers.
