An outstanding cut flower in a shocking shade of blue, Dondo Blue Ageratum truly shines when planted in groups to create a compact, dense flowering bush. Butterflies love them, like all ageratums. Dondo Blue adds easy garden color in borders or containers from summer until frost. Ageratum flowers produce Seuss-like blossoms that are fuzzy and compact. Small in stature but big in interest, Ageratum are ideal border or accent plants as they are heat tolerant and grow no bigger than two feet tall.
