Ageratum Houstonianum - 200 seeds
The Ageratum houstonianum or Floss Flower as it is more commonly known, belongs to the Asteraceae family - the same very special family to which the Daisies, Asters, Gerberas, Chrysanthemums and so many others all belong. It is a Native plant of Mexico. There are many types of Ageratum, but Ageratum houstonianum is the most commonly used in both home and display gardens of all kinds.
Start your ageratum seeds indoors 6 to 8 weeks before your last frost. Once all danger of frost has passed, take your baby plants outside. Transplant them in a sunny location. Remember, this plant loves to be warm. It will develop slowly unless given plenty of rays from the sun.
If you are using your ageratum as a bedding plant, space your plants about 8 inches apart. As the transplants grow, they will fill in quickly. Taller varieties can be spaced further apart.
Ageratum isn’t very choosy about soil conditions, but it won’t do well with soggy feet. Make sure your soil drains well. And don’t let the soil dry out either. Ageratums quickly wilt if conditions are too dry. Because it prefers warmth over cold so much, some suggest watering an ageratum with warm water as opposed to cold. Especially when the plants are young, warm water seems to speed up the growth process of this plant.
