Berkshire, United Kingdom
i have several cosmos in pots ready to go into my garden. i have never grown them before but am surprised by how long the flowers last - not!!!! i am deadheading them everyday! are they always that short lived? and i have read that some are perennial and some bi annual, i thought they were perennial! i actually have about 15 of them so i hope so!!!!
