Among the plants will be pineapple sage and hyssop, which attract hummingbirds or butterflies; selaginella, a groundcover that has color ranging from copper to green to blue-green; tung-oil tree, an unusual medium-sized tree with spectacular flowers in spring; silphium, a tall perennial that draws pollinators and Japanese maple trees.
Cobb County Master Gardeners will be on hand to answer questions. Participants can also get weed advice by bringing a bagged leaf sample from their yard or a photo on a smartphone.
A selection of Bonsai trees will go on sale at 10 a.m. Bonsai Curator Rodney Clemons will answer questions.
Admission is charged, but the cost of admission will be credited toward any plant purchase during the sale or toward the purchase of a Gardens membership.
