Wildflower Greater Knapweed

A great performer for borders, wild gardens and cutting. Nectar-rich flowers are a magnet to bees and butterflies.

How to Sow and Grow

• Sow indoors for surest results, 0.5cm (¼”) deep, in trays of compost.
• Water well and place in a cold frame, unheated greenhouse or on a cool windowsill.
• Seedlings appear in 14-42 days.
• Transplant seedlings 5cm (2”) apart to further trays when large enough to handle. (Always handle by a leaf, never by the stem.)
• Gradually accustom young plants to outside conditions (avoid frosts) before planting out 40cm (16”) apart.
• Sow outdoors in a seed bed, 0.5cm (¼”) deep into finely prepared soil which has already been watered.
• Thin seedlings to 5cm (2”) apart before planting out to flowering positions in spring or autumn, spacing 40cm (16”) apart.
