Description
A long time favorite in our gardens and one the butterflies and pollinators will thank you for planting, Hardy Ageratum is a North American native perennial plant that will provide beautiful late-season color in the garden. Abundant, bright violet-blue flowers massed in flat clusters atop every stem glow in our north central Georgia gardens from September until the first frost in late October or early November. The flowers are perfect for cutting and use in indoor flower arrangements. Excellent for naturalizing along sunny to partially shaded woodland borders, in wild flower gardens, or the periphery of stream of pond.
Landscape & Garden Uses
Growing 3 to 3.5 feet tall and spreading 2 feet or more, Hardy Ageratum excellent for naturalizing along sunny to partially shaded woodland borders, in wild flower gardens, or the periphery of stream of pond.
Suggested Spacing:Â 24 to 36 inches apart
Growing Preferences
Hardy Ageratum is very easy to grow in most any average, medium to wet, well-drained soils in full sun to part shade. It prefers consistently moist, fertile, humusy soils. Plants spread rhizomes and self-seeding to form colonies. Taller plants may be cut back in mid summer to control height.
Plant Long & Prosper!

The Hardy Ageratum (Blue Mistflower) is challenging to locate in my area. The first and last time I saw this beautiful, flowing, colorful plant was in an Amish garden nearly 13 years ago. When the plants arrived, they were packed carefully, amazingly well, vibrant, and healthy! Already they look fabulous after being planted for only a few weeks. I find the entire plant astounding! I am so glad to find Wilson Bros Gardens! They care about their plants, which shows through their care and quality! Suppose you enjoy flowers that require little effort but produce beautiful, vibrant blooms with healthy, lush green foliage. In that case, the Hardy Ageratum (Blue Mistflower) is an attractive choice to enjoy all summer until frost!———————————————————-Wow! Thanks for the kind words and awesome review! We are so glad you are pleased and we hope you enjoy them for years to come! 🙂 Beth Steele | WBG
