In our May insert we cover how to prune lilacs, but I forgot to mentions that when you bring them in as a bouquet, hammer the woody stems. You do this so the flowers can absorb water in the vase. Margret Roach has a great how-to on her blog.
Sensation Lilac - dark purple buds open to white and purple blooms. Striking flowers with and equally powerful lilac scent.
We also brought in a new variety of reblooming lilac this year: Boomerang Lilac. It stays small and keeps blooming!
Donald Wyman Lilacs - the softest pink buds open into almost white blooms.
Miss Kim Lilacs - dark buds open to light pink blooms.
