Pine Knot Farms also has a large listing of Helleborus species, cultivars, hybrids and strains. Haven't tried either of them, so can't comment on quality, size or their service. If you just want to try some Helleborus hybrids or want a mass planting of them, the best value is at Growers Outlet. They are small unbloomed seedlings and colors are unknown, but their price is barely above wholesale cost. If you are looking for unusual colors and/or species, you might try Don Jacobs at ECO Gardens. He has been growing & hybridizing Helleborus for about 25 years.

Pine Knot Farms Hellebores are GORGEOUS, large, beautiful and top quality.

Mary "Go Swimmin'" who sometimes posts to this forum, advertises in the Farmers and Consumers her beautiful, very large hellebores.
