Long-Bloomers That Can Take the Cold Winters
Where winters are long and cold, you need perennials that can stand freezing temperatures but that also bloom and are colorful for a long season, well into fall. In the Northeast and upper Midwest you’re planting right up until the first frost—probably October.
These are some excellent plants to scope out at garden centers for planting right now.
Obsidian Coral Bells
Zone: 4 – 9
Stunningly black, rounded leaves hold their color all season.
Sombrero® Hot Coral Coneflower
Zone: 4 – 9
A must-have for the butterfly or cutting garden, this perennial was bred for cold hardiness and compact form with prolific flowering over an exceptionally long season.
Rozanne Cranesbill
Zone: 4 – 10
As a groundcover, in a pot, or under a bed of roses, its spreading form with dainty violet flowers shows color for many months. Deep green foliage is lightly marbled chartreuse.
EveryDayLily™ Pink Wing Daylily
Zone: 4 – 10
An offspring of the popular Stella de Oro, yet even hardier. Pink and cream flowers have a dark pink halo and yellow throat. Blooms early and steadily season-long.

Early Bird Gold Gloriosa Daisy
Zone: 4 – 10
Breakthrough newer variety that’s day neutral (not dependent on day length to induce flowering). Blooms much earlier and continues to bloom later into the season.
Lacey Blue Russian Sage
