Drifts of Flat Top Aster are stunning in late summer and fall, opening up with clusters of bright white flowers atop tall stems, even in dark woods. This is a great plant for a forest woodline, or any woodland clearing. Flat Top Aster begins blooming earlier than many other aster species, so you can enjoy an even longer floral display by including these in your plantings!

You won't be the only one to enjoy your Flat Top Aster, with it's nectar and pollen extremely attractive to a wide variety of pollinators. It's foliage is also a tasty treat for wildlife (and although we may be sad to lose some leaves here and there, we love seeing our wild turkeys and cottontail rabbits hopping through mature plantings!)

Flat Top Aster was featured as a Top Performer in a Mt Cuba Center Trial Garden Research Report. These reports evaluate native plants and related cultivars for horticultural and ecological value, highlighting the ecosystem services they provide.
