Ratings & Reviews

Coreopsis- Mayfield Giants

This is proving to be a lovely hardy garden plant. I raised seed last spring and transplanted into the garden once it had a few leaves. It flowered magnificently until the frosts hit, made beautiful cut flowers. The clumps of foliage remained throughout hard frosts. Looking forward to them coming into flower again now the weather is warming up. I would love to grow some other colours now!
