Cosmos bipinnatus 'Xanthos'
cosmos
This beautiful annual cosmos has only just been introduced, but it is already starting to win awards! It is the first compact form to have yellow flowers, and these can be used as an accent to strong plums and purples, as well as softening fiery reds and oranges.
Cosmos bipinnatus 'Xanthos' is also said to flower a fraction earlier than many of the others, so if you keep up the dead-heading, you may well have flowers from May to October. Perfect for summer bedding schemes, as well as patio pots, the flowers are also good for cutting.

How to care for Cosmos bipinnatus Xanthos:
Pot on and grow on under glass until all risk of frost has passed and they can be planted outside in a well-prepared bed.
Pinch out the growing tips to encourage bushier growth, and feed at regular intervals throughout summer with a high-potash fertiliser. Taller plants may need supporting with brushwood stems in exposed positions.

Sowing instructions:
In early spring, sow seed shallowly in seed trays and keep under glass, transplanting them into individual pots when large enough to handle. Harden off before planting outside after the frosts.
Alternatively, sow in-situ in mid- to late spring in a well-prepared bed and thin the seedlings out as they grow to allow approximately 30cm between each.
