Feverfew 'Vegmo Snowball'

Tanacetum parthenium

Charming cold-hardy annual producing masses of petite, fully double white button blooms on airy, branching stems—perfect for adding texture, movement and lightness to spring and early summer bouquets.

• Cold hardy and easy to grow
• Masses of double white button blooms
• Flowers naturally as day length increases
• Vigorous branching habit—an exceptional bouquet filler
• Highly productive with a long harvest period

Sown in autumn, Feverfew overwinters beautifully, producing exceptionally long stems and abundant blooms from late spring through summer. The soft buttery-yellow centres add warmth to the crisp white flowers, which float above fresh spring-green foliage.

An indispensable cut flower for the flower farmer and home gardener alike, Feverfew is treasured as a versatile bouquet filler and is equally delightful planted in generous drifts throughout the garden, where it creates a soft, cloud-like display alive with bees and other beneficial insects.

Seed Raising, Growing and Harvest Information

TRANSPLANT(recommended):  Sow 5-7 weeks before transplanting in either autumn or late winter. Surface sow seeds onto growing medium, but do not cover as light aids germination. Bottom water or mist to avoid covering the seed with displaced soil.

Transplant to soil blocks or cells 2-4 weeks after sowing. Harden off before transplanting.

Autumn Planting: For the earliest harvests and the longest stems, sow in autumn and overwinter young plants outdoors or under protection where winters are particularly frosty. Plants established before winter produce exceptionally vigorous spring growth with abundant stems reaching up to 120 cm. Transplant 3–4 weeks before the first expected frost.

Spring Planting: Treat spring-sown feverfew as an annual for the highest quality cut flowers. Early spring transplanting produces long, strong stems and abundant blooms.

Feverfew flowers naturally as day length increases in late spring and early summer. Plants established earlier in the season generally produce taller stems and heavier flowering. Plants will eventually bloom under short-day conditions but on shorter stems.

DIRECT SOW: Sow as soon as the soil can be worked. Press seeds gently onto the soil surface without covering, as light aids germination. Keep the surface evenly moist until seedlings emerge. Thin once the first true leaves appear.

HARVESTING/VASE LIFE: Flowers are prone to wilting, so harvest during the coolest part of the day. Each spray contains a mass of buds.  Harvest when one-quarter to one-half of the flowers on a spray are open.

Place stems immediately into cool water after cutting.  Can be stored in the cooler, but only for a short time.

Feverfew stems quickly cloud vase water, even when floral preservative is used. Refresh the water every day or two. Commercial growers often add a few drops of household bleach to help keep the water clear.

 Expect a vase life of 7-10 days.

To Dry: Harvest when most flowers in the cluster have opened. Hang small bunches upside down in a warm, dark, well-ventilated location until completely dry.
