Ageratum Seed ( Annual )
Ageratum flower, also known as floss flower or Ageratum houstonianum, is an annual garden flower valued for its colorful, long-lasting blooms and ease of care once established. Although easily grown from seed, container-grown ageratum plants are sometimes found in nurseries or garden centers in early spring. One of only a few annuals that can tolerate light shade, ageratum flower thrives with very little maintenance if provided with well-drained soil and adequate water. Ageratum flowers appear in mid-summer through mid-fall in shades of blue, purple, pink and white, depending on variety, although blue blooms are most popular.
Ageratum is an annual except in zones 9 and 10, where it may survive as a perennial.
Start ageratum seeds indoors about 8 to 10 weeks before the final frost in your area, usually around February or March. Fill a seed-starting tray with sterile seed-starting mix. Sprinkle the fine seeds on the surface of the soil and tamp them down, but don't cover with soil, as light is required for germination.
