Cosmos bipinnatus 'Razzmatazz Series'
cosmos
Yellow-eyed daisy-like flowers, which have a soft spiky appearance, top upright stems throughout the summer, putting on an impressive display in the border (or large pots).
Cosmos bipinnatus 'Razzmatazz Series' comes in a range of colours, from white to deep pink - with picotees as well - so will mix easily with a whole host of colours. Once established, these cultivars are generous bloomers, and if the flowers are cut for the vase, it will encourage even more to form.

How to care for Cosmos bipinnatus Razzmatazz Series:
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.
