Floss Flower 'Blue Horizon'
Floss Flower is a charming annual that provides a continuous display of soft, fluffy blue, purple, pink, or white flowers throughout the summer in UK gardens. Its compact, mounding habit makes it ideal for edging borders, mass planting, and containers. It’s a half-hardy annual, typically sown indoors in spring and planted out after the last frost. Ageratum thrives in full sun to partial shade and moist, well-drained soil. Regular deadheading encourages more blooms, ensuring a long-lasting and vibrant display. Its unique texture and often striking blue colour make it a valuable plant for adding depth and softening other bedding plants.
