Cosmos

in

Large, delicate flowers and lacy, fernlike foliage make a great addition to the middle of the flower bed or cutting garden. Eye-catching along walls or fences. Spent flowers may be removed to encourage rebloom, but allow some to go to seed as cosmos readily self-seeds. Tolerates poor, dry soil.
