Description / Dondo Blue Ageratum Seeds
Dondo Blue Ageratum is a mounding annual known for its dense clusters of soft, powder-blue flowers that bloom continuously from early summer to frost. Reaching 18 to 24 inches tall and 10 to 12 inches wide, this variety offers a tidy, uniform habit perfect for beds, containers, and the cutting garden. The fluffy, button-like blooms are long-lasting, weather-tolerant, and highly attractive to pollinators such as butterflies and bees. Dondo Blue Ageratum also makes outstanding cutflowers and is valued for its strong branching and early flowering, providing a reliable burst of cool-toned color throughout the hottest months of the year.
Commonly called Floss Flower, Dondo Blue Ageratum is an excellent choice for front-of-border plantings, mixed containers, window boxes, and even mass plantings where a carpet of color is desired. Its soft blue blooms pair beautifully with warm-toned companions like marigolds, zinnias, salvia, and snapdragons, or with other cool hues like dusty miller and white alyssum for a more serene look. The flowers are also suitable for cutflower arrangements and can add a whimsical touch to garden bouquets.
Best grown in full sun to partial shade, Dondo Blue Ageratum thrives in rich, well-drained soil with consistent moisture. Direct sow seeds after last frost date or start seeds indoors 8 to 10 weeks before the last frost date and transplant into the garden once the threat of frost has passed. It's a low-maintenance annual that's deer-resistant and highly adaptable to various growing conditions. Ideal for small spaces and high-impact displays, it's a standout among blue-flowering annuals.
