Ageratum Bumble Blue, 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 Blue flourishes in full sun with an upright mounding habit of 8-12 inches. Floss Flower's blue blooms attract butterflies, bees, and hummingbirds from May through September. Ageratum makes beautiful containers and borders. Combine Bumble Blue with Salvia, Vinca, Angelonia, Begonia, Marigold, and Petunia to create a welcoming landscape.
Bumble Blue Selling Tips
Sell Ageratum Bumble to any customer looking for a low-maintenance annual to add to a container or landscape border. Floss Flower succeeds in full sun with plenty of heat and is outstandingly vigorous. Flowers bloom continuously from spring through fall with no deadheading. Even in high temperatures, this plant requires little more than moderate water. Ageratum Bumble provides ornamental interest without adding to your customer's gardening maintenance. Bumble Blue brings pollinators to the garden as well. Combine Ageratum Bumble Blue with Rose, Silver, or White to add depth and variety to containers.

General Growing Tips For Your Rooted Cutting Liner
For best results with Ageratum Bumble, use well-drained soil in full sun with medium feed (150-200 ppm), a pH of 6.0-6.5, and an EC of .6-.9. Plant one rooted liner per 4-inch container or two to three plugs per 10-inch pot. Maintain daytime temperatures of 70-80 degrees and nighttime temperatures of 58-62 degrees during finishing. You may see aphids or whiteflies. This plant can be susceptible to powdery mildew.

Pinching
Pinch once after transplanting.

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 Blue 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.

Before we take this relationship any further...
It looks like this is the first time you've added anything to your cart.
We just wanted to remind you that we are a wholesale starter plant company that sells to businesses, schools, clubs, and other non-profits. State law dictates that you must be growing for resale to order from us since we are not collecting sales tax.
If we aren't a match, we understand. It's not you, it's us.
We would look awful in orange jumpsuits.
