Sow and Plant
Sow seeds indoors in late spring and set plants out after the last frost has passed. Seedlings are sometimes available as bedding plants.
Strawflowers are among the best annuals to grow and dry for use in winter arrangements. Colors include yellow, pink, orange, red and white, all with yellow-orange centers.
Cut blossoms as soon as they open and hang to dry in small bunches.
Choose tall varieties with long stems for drying. Persistent wet conditions can cause strawflowers to rot.
