Cosmos ‘Rosetta’

Cosmos bipinnatus

This a unique new variety looks almost hand painted.  Cosmos ‘Rosetta’ has petals splashed with rosey pink stripes!

No cutting garden would be complete without a patch of Cosmos!  With long strong stems and abundant romantic blooms, its cut and come again. Regular harvesting will keep your plants producing bucketfuls of blooms through the season.

Perfect for garden decoration too, delicate blooms dance in the breeze attracting bees and butterflies.

With so many varieties available it can be hard to choose. Cosmos ‘Rosetta’ is among my current top choices and the ones I will be including in my cut flower garden this year.

How to grow

Don’t start Cosmos too early, these half hardy plants cannot be planted until all risk of frost has passed. Sow under cover in mid spring and plant out after the last frosts, or direct sow early May… For more detailed growing instructions join our ‘Grow Along’ on Instagram
