A cornflower variety with so many petals it turns into a blue powder-puff. Multiple this with the many blooms it puts up and you have intense blue lagoon of pretty but punchy blooms.

Gorgeous together with other wildflowers like poppies and corncockles, for bags of colour and form in your wildflower patch. Equally good in containers.

How to grow

Sow seeds on to the surface of pre-watered seed compost, but don't cover them. Keep warm, around 20°C and keep moist, but not wet. Allow 1-2 weeks for germination.
