Feverfew 'Tetra White'

Feverfew – Tetra White (Tanacetum parthenium, formerly Chrysanthemum parthenium)

Tetra White is a prolific and reliable cut flower variety, producing masses of fully double, ¾–1" daisy-like blooms. Flowers are a clean, bright white with fresh citrus-yellow to lime-green centres, held on strong, branching stems that bloom in a uniform canopy atop compact plants.

Similar in timing, growth habit, and productivity to the popular Magic series, Tetra White feverfew is ideal for market bouquets, borders, and floral design work. The delicate, button-like blooms add a fresh, vintage look to arrangements and dry beautifully for everlasting displays.

This variety is also known as Matricaria, or Featherfew, and has a long history of use in both gardens and traditional herbal medicine. Foliage is aromatic and fern-like, adding additional interest and texture.

Tender or short-lived perennial in Zones 5–9. Often grown as an annual in cooler regions.

How to Grow:

Transplant (recommended):
Sow indoors 5–7 weeks before transplanting out in spring or fall. Press seeds gently into the surface of the soil—do not cover, as light aids germination. Bottom water or mist to avoid displacing seeds. Transplant into cell packs or 3–4" pots 2–4 weeks after sowing. Harden off before planting outdoors.

• Fall Planting: For the longest stems and earliest blooms, transplant 3–4 weeks before first frost. Overwinter young plants in a high tunnel for spring harvests up to 48" tall.

• Spring Planting: Treat as an annual for optimal flower and stem quality. Early spring planting under row cover or in tunnels will yield abundant blooms.

Direct seed:
Sow outdoors as soon as soil can be worked. Press seeds into soil surface without covering. Keep moist until germination. Thin seedlings once true leaves appear.

Pinching: Pinching the central stem of young plants when they are about 6–8 inches tall will encourage branching and more stems. Deadhead spent flowers to prolong the blooming season and prevent heavy self-seeding.

Soil Preference and Watering: Feverfew thrives in full sun and prefers well-drained soil. It is drought-tolerant once established and does not perform well in overly wet conditions.

Fertilizing: Fertilizing is not required for Feverfew. It performs best in average to lean soil.

Harvesting: For bouquets, harvest stems when the flowers are about halfway open. Harvesting at this stage ensures a long vase life.
