Statice likes good drainage and deep, sandy loam, so consider working in a spadeful or two of sand. A slope, raised bed or other well-drained site is also a good choice. Plant outdoors in spring after all danger of frost has passed. Space 8 to 10 inches apart. Keep soil a little on the dry side.
Statice likes it that way.
Trim faded flowers or cut bouquets frequently to promote longer bloom. Tear out and discard plants after frost fells them in fall. If drying statice, cut the flowers just after they open for best results and brightest, clearest colors. Read the label carefully so you know which type you're purchasing. Inc. How things get done.
