How to Plant, Grow, and Care for Lilac Shrubs
Lilac flowers are edible, but flavor varies among cultivars from no flavor to “green” and lemony flavor. Gather insect- and disease-free blooms early in the day. Avoid any that are unopened or past their peak. Wash the flowers gently in cool water. Pat them dry and refrigerate until ready to use.
Consider making candied lilac flowerets for a special cake decoration: Separate the individual flowers. Using tweezers, dip each one into a beaten egg white, reconstituted egg white powder, or packaged egg whites. Then dip the flower in finely granulated sugar. Set it aside to dry before placing it on a cake.
