All these easy-to-grow flowers are sun lovers, all are treated as annuals in regions with cold winters, and all thrive in moist but well-drained soil. Unless otherwise noted, cut when blossoms are new and unblemished. Harvest on a dry day after the dew has evaporated but before afternoon sun causes wilting. Because flowers shrink when dried, cut more than you think you'll need. After cutting, remove excess foliage, and hang the flowers in small bunches in a warm, dry, airy place away from the sun. Drying times given are for dry, sunny weather. Depending on conditions, drying could last a few more days.
