Cosmos 'Sea Shells'

Plant details

Daisy-like cosmos flowers are easy-to-grow and versatile annuals. They can be used to plug gaps in borders, grown as a feature in their own right or as part of a container display. The flowers attract a variety of bees, butterflies and hoverflies, and also make a good cut flower.

Cosmos 'Sea Shells' has interesting fluted petals, each rolled round a tube, like a sea shell. It makes a great planting partner for dark-flowered dahlias and chrysanthemums, and both its flowers and foliage work well in cut flower arrangements. For best results grow Cosmos 'Sea Shells' in moist but well-drained soil, in full sun. Deadhead spent flowers to encourage repeat-flowering.

This year is my first time at growing Cosmos 'Seashells', the seedlings have so far grown into healthy sturdy young plants, promising lots of radiant blooms.

at what stage do you plant out & they are big enough not to get eaten..I landed up with just one plant this year...
