I’m going to give the prize for the best performing perennial of the year to this Chocolate Cosmos, whose official name is Cosmos atrosanguineus “Chocamocha”, and names don’t come more splendid than that. I bought a few plants of it in June from Cath’s Garden Plants, ( http://www.cathsgardenplants.co.uk/) who are just down the road from us at Heaves and they have been in flower from then until now with no sign of giving up. We’ve had a few frosts, which they have shrugged off. This photo was taken today and it’s astonishing that there are not only lots of flowers in bloom but also masses of buds. We haven’t paid it the slightest attention since it was planted, so it has performed this well without any dead-heading. In the past I’ve had difficulty getting this plant through the winter in the ground, but I’m going to follow Cath’s advice and give it a good mulch, and hope for the best.
It’s not called Chocolate Cosmos for nothing- the flowers smell strongly of chocolate.
