Comparing Cosmos varieties — notes from growing several

I've grown several varieties within the Cosmos family and have some observations to share. exceptional wildlife value for bees, butterflies, and hoverflies varies noticeably between them, more than catalogue descriptions suggest. The care fundamentals are shared — allowing plants to set seed before cutting at the end of season applies across all of them.

dog walkers or trampling on unmown meadow areas affects some more than others, particularly in adverse conditions. I grow mine in a container with a meadow mix for a balcony which works well for most varieties. early spring bulbs and annual seedling germination is the clearest moment of differentiation between varieties — that's when the character of each comes through. Worth growing a few side by side if you have the space.
