Description
  • The world's first yellow summer Cosmos
  • This year's must-have bedding plant!
  • Compact and early flowering
  • Garden performance guaranteed

The world has been waiting for a summer-flowering yellow Cosmos, and here it is! Adding an exciting new colour to the Cosmos palette, Xanthos (meaning yellow in Greek) produces exceptional, branching plants with a heavy supply of 5cm (2") blooms from May right through to October. Keep on top of deadheading and new flowers will just keep coming.

Cosmos 'Xanthos' features soft ferny foliage, which quickly and easily fills space in the border, even before the yellow blooms appear! Unusually for Cosmos, 'Xanthos' look great in patio pots too! New on the scene Cosmos 'Xanthos' has already picked up a Fleuroselect Gold Award and evoked much customer comment in T&M's summer trial garden in 2015.

Use the classy blooms en masse for an elegant feel to your displays, if not, set them in combination with other annuals to complement pastel shades or contrast with hot colours. The stand-out flowers also make a great underplanting to shrubs and hedging. These compact cosmos plants are the perfect option for exposed gardens where taller varieties would be blown about by the wind. Height: 60cm (24"). Spread: 40cm (16").

How to Grow
Pot up cosmos plants and grow them on in warm, frost free conditions until large enough to plant outdoors. When all risk of frost has passed, gradually acclimatise cosmos plants to outdoor conditions over 7 to 10 days before planting out in beds, borders and containers. Choose a position in full sun on any moist, well drained soil.
More Info
When growing Cosmos plants, water regularly until they are fully established. Deadhead faded Cosmos flowers regularly to encourage more blooms to be produced throughout the summer.
