Top 5 Perennials for Late Season Interest

Create an autumn color show in your garden with perennials that come into their own late in the season. Asters, Ornamental Grasses, Rudbeckias, Russian Sage, and Echinaceas are among the plants that put on a brilliant display in the fall.

1. Aster x frikartii ‘Monch’

Aster x frikartii 'Monch'

Its graceful 2-3′ stems bear masses of 2½″ flowers all summer, in an extraordinary shade of lavender blue. An outstanding middle of the border plant with Achillea, Alchemilla, Alstroemeria, Antirrhinum, and Astrantia.

 

2. Calamagrostis ‘Karl Foerster’

Ornamental Grass: Calamagrostis x acutiflora 'Karl Foerster'

Also knows as Feather Reed Grass, Calamagrostis ‘Karl Foerster’ is one of our favorites because of its upright habit and good manners. It forms neat clumps of foliage 18–24″ tall. In June, the toasty brown, feathery flower spikes rise up to 5′ or more. By August they are narrow shafts of a buff color. Consider summer and fall-blooming perennials as companions: Achillea, Rudbeckia, Helenium, Asters, Monarda, Perovskia, Phlox, and Oriental Lilies.

 

3. Rudbeckia fulgida sullivantii ‘Goldsturm’

Rudbeckia fulgida sullivantii 'Goldsturm'

The Black-eyed Susan, is a glorious and traditional highlight of summer. While the native plant is enchanting, ‘Goldsturm’ improves upon an already good thing by providing more and bigger flowers in a consistent bright golden yellow on upright plants that reach 40″. Plant with Salvia, Phlox, Asters, or Perovskia.

 

4. Perovskia atriplicifolia ‘Blue Jean Baby’

Perovskia atriplicifolia 'Blue Jean Baby'

Topping out at 30-36″, this hardy, compact Russian Sage is a great choice for anyone whose garden is too small for the original Perovskia atriplicifolia which can grow to 3-4′ tall. Stems of silver-green foliage with small purple flowers erupt in a lilac haze in midsummer and the color lasts until fall. Companions include: Hydrangea, Salvia, Phlox, & Echinacea.

 

5. Echinacea purpurea ‘Magnus’

Echinacea purpurea 'Magnus'

We find real value in this popular variety. The petals are an especially vibrant carmine-rose shade and are held almost horizontally, making a more open face than the shuttlecock shape of the species. Lovely with the blue wands of Perovskia.

Every garden needs a sampling of easy-care, late-season stars to maximize the season of bloom and carry the garden into fall. A number of the plants on our Late Season Interest Plants page also provide essential food for pollinators, who need nourishment and support as the season nears its end.

Need a shrub or two to complete your late season garden? Hydrangeas are at their best in summer and fall—a quiet time for most woody plants—and are worth having for that reason alone. You’ll find the full range of Hydrangeas we offer here.
