25 Seeds Ageratum houstonianum Dwarf Blue Mink

Ageratum houstonianum, commonly called floss flower, is a compact annual prized for its fuzzy, powder-puff blooms in a soft blue-mink shade. Dwarf Blue Mink stays low and tidy, making it a dependable choice for edging, borders, and container plantings where its long-lasting color carries through the season.
This easy-going annual works well massed in beds, tucked along walkways, or blended into mixed containers and hanging baskets. The dense, mounded habit and fluffy flower clusters provide steady color from early summer into fall, and the blooms are a favorite for cutting.
