One of the easiest plants to grow and one of the most reliable to flower and put on a great show all summer is Cosmos. I think my favourite is ‘Purity’ simply because it has such pure white flowers which highlight and accentuate the rich colours of other plants.
This year I tried a couple of new varieties from which I will collect seed, the unusual ‘Double Click Cranberry’ and the pretty ‘Picotee’ with delightful pinky purple edges.
The taller varieties can get a bit ‘top heavy’ and begin to lean or even topple over in high winds but they usually survive if pushed back up and staked. The shorter varieties make colourful front of border plants. They are all very attractive to pollinating insects, flower for months if deadheaded regularly, are drought tolerant and will grow in almost any soil. What more could any gardener ask for?
