High-quality, cool season cut flower. Conventional seed with conventional pelleting. This seed is not NOP-compliant.

2–5″ rounded clusters of single-petaled, pure white blooms on long, strong stems. Bred for greenhouse and high-tunnel production but also suitable for open field. Demonstrated excellent performance overall in our fall-planted, overwintered and unheated tunnel trial; it bloomed about 4 weeks earlier than Amazon. Plant vernalization is not required to initiate flowering. Fragrant blooms. Plants are high yielding, producing long-lasting blooms, up to 14 days. Tender perennial in Zones 6–8. Pelleted seeds.

Specs:

  • Plant Height: 18–36″
  • Packet: 25 seeds
  • Avg. 13,400 seeds/oz

Size

Packet, 250 Seeds, 1,000 Seeds

DAYS TO GERMINATION

7-14 days at 65-72°F (18-22°C)

SOWING

Transplant (recommended) – Sow 6-8 weeks before last frost. Lightly press seed into growing medium. Transplant into cell packs or 3-4" containers 20-25 days after sowing. Harden off and transplant out 6-8 weeks after sowing. Cool temperatures of 50-55°F (10-13°C) are required to keep the plants low growing and basal branching. Avoid warm temperatures in excess of 65°F (18°C), especially at night, which will produce soft growth. Direct seed – Early spring when a light frost is still possible.

LIGHT PREFERENCE

Sun.

PLANT HEIGHT

Varies.

PLANT SPACING

6".

HARDINESS ZONES

Zones 6-8. Best results when planted as an annual.

HARVEST

10-20% of flowers in cluster or spray are open.

SOIL REQUIREMENTS

USES

Excellent commercial cut flower and is also suitable for gallon container production with one plant per gallon container. Also makes a lovely bedding plant.

PELLETED SEED

If using pelleted seed, we recommend consistent soil moisture during the germination period. Pelleted seed must be kept cool and dry prior to planting, and should be used within one year of purchase.
