Cosmonaut has pretty green, feathery foliage
From summer through to autumn the upright stems carry masses of pure white, semi-double flowers.
It is earlier to bloom than most other cosmos and it's tall, elegant habit makes it perfect for mixed borders and cottage gardens alike. It can be used as a delightful flowering screen or informal hedge for the summer!

How to Guide
Almost fill a seed tray with moist seed compost. Sow seeds thinly over the surface, and lightly cover them with a little more compost. Place in warmth 15-20C (60-70F), and keep moist.
Sowing Distance45cm / 18in
Potting on/Thining Out
Keep seedlings in a light position, but shade from bright sun. When large enough to handle transplant 5cm (2in) apart into trays of potting compost.
Hardening Off/Planting Out
Gradually accustom plants to outside conditions for 2-3 weeks before planting out when danger of frost has passed. Allow 45cm (18in) between plants.
