Centaurea 'Snowy Owl'(PBR)
This Silver Knapweed is a magical addition to any garden, with its large, velvety, silver leaves that contrast beautifully in mixed borders or patio pots. Throughout summer vibrant yellow, thistle like flowers provide even more light and colour. Loved by garden pollinators. Drought tolerant.
Grow in patio containers, or plant into any average garden soil, avoiding wet areas. Cut out any dead flowers as they fade. May need some winter protection.
Water thoroughly, or stand pot in a container of water for half an hour before planting. Dig a hole twice the size of the root ball. Remove the pot, place the plant in the hole so that the root ball is level with the surrounding ground and refill, firming if necessary. Feed in spring with a good, general fertiliser.
July - September
