Cosmos is one of my absolute favourite plants. It gives you the highest square-inch productivity of any cut flower, so for every square foot that you plant, you’ll get more buckets of cut flowers from that square foot than you will with any other plant.
Cosmos bipinnatus ‘Purity’ has large, open flowers of pure white, with delicate apple-green foliage. It’s the classic cut flower and a supremely lovely garden plant that no one should be without. For a belt of brightness try Cosmos ‘Dazzler’, which has large, open, buttercup-like flowers of carmine with delicate, feathery foliage – it’s beautiful, tall and airy.
Cosmos lasts 10 days in a vase, produces at least two buckets of cut flowers a week from a one-metresquare patch and is in bloom from late June…
