Cosmos bipinnatus 'Sea Shells Mix' / Seeds

An unusual variety of Cosmos with a mix of fluted shell-like flowers in red, pink and white.  Flowers come out from June/July all the way to October.  Plants grow to a good height of 90-120cm, and are surrounded by attractive feathery leaves.  Flowering continues to the first frosts with dead heading.  These make good border plants and cut flowers.

Cosmos ‘Seashells Mix’ grows best in full sun and moist well drained soil.  Plants are attractive to pollinators.

Pack of approx 150 seeds.  Sow indoors from March to May, or directly in the ground once all risk of frost has passed (May to June depending on where you are in the UK).  Sowing instructions and a colour photo are printed on the packet.
