cosmos
This beautiful, half-hardy annual delivers a prolonged display of colour in the garden.
An upright, bushy plant with finely-divided, bright green leaves, Cosmos bipinnatus 'Antiquity' requires little to no staking and bears masses of crimson to burgundy, daisy-like flowers, which mature to sepia-bronze over time.
Perfect for pots and very floriferous, it also delivers plenty of long-lasting (up to 10 days) cut flowers for the vase.

How to care for Cosmos bipinnatus Antiquity:
Pot up 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.
