Cosmos, Carly's Pink Seeds

Uxbridge Township’s flower!

These delightful beauties in cheery pinks (my favourite colour!) are showstoppers in my full sun gardens. 

Daisy-like blooms sit atop long, slender stems with feathery leaves, forming a cloud of colour. Once blooming, you’ll have non-stop flowers until a hard frost.

They crawl with bumblebees, hoverflies, sweat bees and ladybugs; I love sitting quiet and close to a patch of Cosmos, listening to soft buzzing and watching the action. Small birds such as goldfinches and chickadees eat seeds from the dried flower heads.

An excellent cut flower, lasting a week or more. East Gwillimbury Garden Club 3rd place winner in 2023, any other annuals category.

Open-pollinated

Heirloom

Mix of single, double and fluted blooms

Carly’s Tip: Water soil first, let saturate, then plant seeds. This prevent seeds – especially light, delicate ones not deeply sown – from moving/washing away.
