Description
A whimsical twist on the classic cosmos, Seashells produces delicate, airy blooms with uniquely rolled petals that resemble seashells. The soft, fluttering flowers dance above tall stems, bringing a cottage-garden charm to the landscape. A wonderful choice for cutting, these blooms add movement, texture, and a touch of nostalgia to bouquets and arrangements. Let them weave through the garden for a dreamy look, or gather armfuls for a vase—the more you cut, the more they’ll bloom.

Start seeds indoors 4-6 weeks before your last frost date. Place in a warm area to germinate. Plant outdoors once chances of frost have passed. Seeds can also be direct sowed in the garden. Cosmos can tolerate some cool weather. Pinch plants once they've reached 12 inches to encourage branching and more blooms.
Harvesting
Cosmos flowers should be harvested at the 'cracking bud stage' when the buds are coloured but not yet fully open, or when the first few petals have just begun to unfurl. This stage ensures a longer vase life and allows the blooms to fully open after being cut.
