Ageratum houstonianum ‘Aloha Blue’

For those of us looking to add some whimsical color and shape to our gardens, this week’s feature will be just the ticket! Ageratum houstonianum, commonly known as ‘Flossflower’, is a lovely annual native to Central America and the West Indies with blue-lavender blooms and deep green heart-shaped leaves. The blooms are uniquely wispy in shape, looking much like spindly powder puffs. As a dwarf series of Ageratum, ‘Aloha Blue’ grows in 6-8 inch wide mounds reaching 4-6 inches height.


This low growing Ageratum is an excellent choice for group planting along borders, in mixed containers, and in pattern designs. Pairing with other warmer colored flowers will provide stunning contrast to your landscape. ‘Aloha Blue’ thrives in partial shade to full sun, though full sun is only appropriate in cooler climates. The New Sunset Western Garden Book deems Zones 1-24 as suitable for growing. Regular watering and occasional upkeep through removing spent blooms will keep Ageratum looking vibrant late into the season.


We currently have Ageratum houstonianum ‘Aloha Blue’ growing in 6-packs. It was added to our availability last week and is going quickly! To learn more about this plant and the many others we have looking top-notch in these warming Spring temperatures, don’t hesitate to give us a call.
