Please Note: Container-grown Cosmos can naturally be very floppy in habit. This is nothing to be concerned about when you receive your plant. Once in the ground, they become a much more stable plant. Please do not be worried if some of the outer stems become detatched in transit. This will have no detrimental effect on the future performance of the plant.
