I hope everything is going well with you. I have only been growing Cosmos for the last two years and I have come across a variety 'picotee' which produces a single flower on a relatively long stem. This is great (easy) for deadheading as I just use scissors and let it drop on the bed as opposed to those which have multiple buds close to each other and require precision cutting. Picotee is a white petal with red/pink edging. Does anyone know of another cosmos which has the same habit but possibly more dramatic colouring?
