Frostweed

A pollinator favorite that brings winter magic to your garden. Frostweed grows tall and proud in the late-season landscape, producing clusters of bright white flowers from late summer into fall—right when pollinators like monarchs need them most. In winter, this statuesque perennial performs an encore act: when the first hard freezes hit, its stems crack open and release delicate ribbons of ice that curl and spiral like spun glass. It's one of the few native plants that dazzles even after blooming ends.

Frostweed thrives in full sun to part shade and is well-suited for naturalistic plantings, back-of-bed borders, or moist woodland edges. Its height and seasonal drama make it a bold, ecological choice for pollinator gardens.

Why Choose Frostweed?

• Offers vital late-season nectar for monarchs and other fall pollinators.
• Produces unique “frost flowers” in winter—a rare natural spectacle.
• Great for woodland edges, moist meadows, and informal gardens.
• Spreads gently by rhizome and seed to naturalize large spaces.
• Tolerates a range of soil types and handles seasonal moisture well.
  

Frostweed is low-maintenance—cut stems to the ground in late winter after the frost flowers have formed. Allow some room for spreading, or thin clumps every few years if needed.

• Cut back stems in late winter or early spring, after frost flower formation.
• May spread aggressively in rich soils—thin or divide as needed.
• Tolerates part sun but flowers best in full sun with medium to moist soils.
