‘Red Sea’ Ageratum (Ageratum houstonianum)
This tall ageratum offers long stems perfect for plucking and plunking into vases. Fuzzy flowers shift through purple shades from deeply tinted buds to pastel faded blooms. Plants reach 24 to 30 inches tall and are deer-resistant. The more you pick, the more blossoms you’ll see.
