Buy Cosmos Plug Plants & Seedlings

Sarah Raven offer only the highest quality cosmos plug plants and seedlings for sale. Buy your plants online and they’ll be delivered right to your door. From classic white cosmos flowers to the velvet textured and mahogany brown tones of chocolate cosmos flowers, we have a wide range of beautiful cosmos flowers to suit every taste.

Our cosmos plants are available to buy as seedlings and jumbo seedlings, grown exclusively for us by our nursery in Lincolnshire. We’ve done the tricky part, sowing the seed and making sure they’re growing strongly, all you have to do is put them in the ground.

Cosmos plants are highly productive, extremely low maintenance and a favourite with bees and butterflies. A 1m x 1m flower patch will produce at least two buckets of flowers a week – that’s nearly 50 bunches in one season! Deadhead the plants regularly and they will flower until the first frosts.

All of our cosmos flowers are trialled in Sarah’s garden at Perch Hill and chosen for their quality. Every order comes with detailed planting instructions. We also have a fantastic range of cosmos seeds for sale online.
