Ageratum houstonianum, known as flossflower, is a popular herbaceous annual featuring a neat, mounded growth habit. Reaching heights of 6 to 24 inches, it displays soft, ovate green foliage and unique, fluffy flower heads in shades of blue, purple, or white. These blooms appear from late spring through fall, attracting various pollinators. Ideal for borders, containers, and rock gardens, it thrives in full sun to light shade and requires rich, well-draining soil with consistent moisture.
