How To Grow
GROWER TIP: Some growers soak the seed in warm water for a few hours prior to sowing. This isn’t required but can lead to better germination. If started indoors, use biodegradable CowPots, sowing 1 seed per pot, 8 weeks prior to the last frost. Transplant or direct sow when temperatures are at least 65°F. Biennials will grow a strong root system in their first year, later wilting on the surface with frost, only to return and flower in its second season.
