Red Flint

Ageratum Seeds

Red Flint ageratum blooms in an unusual color palette for ageratums, warm shades of rose-pink to magenta-red.  Clusters of ¼ in. fluffy flowers atop 24 in. straight, sturdy stems are long-lasting in fresh cut and dried arrangements. Red Flint looks beautiful summer through fall in sunny garden borders as well as in mixed containers, where the fine, floss-like texture contrasts well with bold summer annuals like zinnias, marigolds, and petunias.
