Reliable with very attractive flowers. I have bought Cosmos Purity seeds year after year to climb up our willow arches and they have never failed to give us a stunning display. We also planted some under a redundant sweet pea frame in very different soil conditions and they did incredibly well there too. I always start our seeds in trays in the polytunnel, thin them out into individual polypots, harden them off in the cold frame and plant them in their final growing position when all chance of frost has passed.

Sunnybank

Lancashire

Masses of pretty large white flowers over a long period, interesting folliage, quite tall plants, may need staking of some sort especially in high winds, make an impact late in the season, got compliments from visiting friends

Easy to grow from seed but as slugs like the young,plants I tend to grow them on in pots until strong. Once established they flower continuously. Pure white flowers and feathery foliage. They do need staking as the plants grow very large. I wouldn't be without them. They will flower almost to first frosts

Pink nasturtium

South wales

Planted seeds in trays covered as directed. Placed inside the house and kept moist. Only 4 out of 15 are now seedlings and have been potted on successfully.

Creates a magical effect in large pots or the border throughout late summer. Beloved of bees.

The plants that survived the slugs flowered well into Autumn, I love them!
