Reviewed 4th October 2017 by Marie Clements

This has been a lovely collection. The flowers have been delicate and prolific all summer. As I said in my review for the Cosmos and Nicotiana Collection it would be great if Sarah could add a bit in her video about how to pinch out Cosmos plants so they don't get too tall as mine have got quite tall (needing tall canes) and bushy - please don't assume we all know which bits to pinch - but despite my lack of pinching out they have flowered wonderfully and been a delight all summer and still have flowers now in first week of October. Very simple to grow on and plant out in both beds and pots. Dead heading is easy once you have watched Sarah's helpful video. A rewarding plant for the newby gardener. I would definitely buy this collection again.
