Sow this mix of annuals in mid spring. Mix consists of Dahlia Zinnias, Sea Shell Cosmos, Bishop's Lace, Feverfew, and Snapdragons. To make a stunning bouquet, choose flowers that have recently opened or are about to open. With sharp shears, cut the flowers with as long a stem as you can. Snip off any leaves or sideshoots from the stems. Arrange the zinnias, cosmos, and bishop's flower in your hand with tall flowers in the middle and shorter and wider flowers around the edges. Cut the bouquet to the shortest stem length.
