The fuzzy blue flowers of hardy ageratum top attractive red stems in late summer and early fall. Easy to grow, it naturalizes readily and works well as a filler or groundcover planting. Its brilliant blue flowers make a unique and long-lasting cut flower. In warmer zones and loose soils, plan for quite a bit of spreading.


  • Flowers attract bees, butterflies, and skippers
  • Easy to grow, flowers from mid-summer into autumn
  • Makes a great groundcover
  • Attracts insects favored by birds

In addition to butterflies, late summer and fall blooming asteraceae species provide food for many insects, some of which are in turn food for insect-eating birds like Bluebirds, Orioles, Warblers and Red-wing Blackbirds.



Mistflower is adapted to most soil types, but is especially suited to heavy soil rich in organic matter. Natural stands are found on moist to wet sites, such as low woods, wet meadows, and ditches. It grows best in full sun, but will tolerate light shade.

    Quick Tips for Choosing Plants:

    • Planting a variety of native trees, shrubs, perennials and vines increases biodiversity and gives wildlife a source for food, cover and nesting
    • Choose a mixture of deciduous and evergreen trees so birds and other wildlife will always be able to find shelter
    • Plant trees and large shrubs where they will block winter winds from the house and shade it in summer, that will save energy and lower your carbon footprint
    • Try your best to buy plants that were grown locally, your independent garden center will be your best bet
    • Think about ultimate height and width of the plant you choose, make sure it will fit the space you have for it when it's reached maturity
    • Plant nectar plants in groups, to attract butterflies and other beneficial insects more easily
    • Ask for help if you need it. Most garden centers either have a landscape designer on staff or they can give you a reference of a designer that is adept at native plant wildlife gardening. There will be upfront costs but they are small when compared to having to redo a landscape that wasn't what you really wanted

While the “Benefits” section talks about the plants strong suits and how the plant will benefit wildlife. 

    A Special Note About Exposure

    Full sun: Prefers six or more hours of direct sunshine a day
    Partial shade: Thrives in three to six hours of daily sunshine
    Shade: Generally does well with less than three hours of sun per day. Having said that even shade loving plants will struggle in extremely deep shade.
