Ageratum Bumble White, also known as Ageratum Houstonianum or Floss Flower, is an annual native to Mexico. Westhoff developed this Ageratum hybrid to offer superior flowering and uniform growth. Bumble White flourishes in full sun with an upright mounding habit of 8-12 inches. Floss Flower's white blooms attract butterflies, bees, and hummingbirds from May through September. Ageratum makes beautiful containers and borders. Combine Bumble White with Salvia, Vinca, Angelonia, Begonia, Marigold, and Petunia to create a welcoming landscape.

Disease
Ageratum Bumble can be susceptible to powdery mildew, especially during humid nights and cool days. Take these preventative steps to protect your plants:
1. Water plants in the morning at the base to allow them to dry out by nighttime.
2. Provide adequate ventilation by spacing plants and use horizontal airflow fans to increase airflow.
3. Grow plants in full sun.
Planting Bumble White Liners
We recommend planting one liner per 4-inch container or two-three liners per 10-inch container. Use well-drained soil and completely bury the ellepot centered or equally spaced in your pot.
Rooted Cuttings
Cuttings vary in size between different plant families. These rooted starter plants will arrive ready to be transplanted in to your final container. If they are to be used in a landscape application, you will need to establish them in a 4 inch pot or an 1801 before planting outside.
