A Frosty Masterpiece of Seasonal Brilliance
Hosta 'Autumn Frost' is a show-stopping, medium to large cultivar that brings a high-definition "glow" to the Canadian shade garden. A prized sport of the legendary 'First Frost' and part of the "Shadowland" collection from Walters Gardens, this variety takes variegation to the extreme. It features extra-wide, consistent margins that emerge a brilliant, sun-drenched yellow in the spring before maturing into a clean, parchment white. The centre of each heart-shaped leaf is a rich, frosty blue-green, creating a sophisticated "halo" effect that holds its crisp definition from the first spring thaw in Bécancour right through the arrival of the autumn frosts.
Why It Stands Out
-
Extra-Wide Luminous Margins: The thick, yellow-to-white borders occupy a significant portion of the leaf, illuminating even the deepest shade.
-
Steadfast Blue-Green Heart: Features a heavy waxy bloom in the centre that provides a cool, frosty contrast to the bright edges.
-
Elite Leaf Substance: The foliage is remarkably thick and leathery, providing superior durability and excellent resistance to slugs and snails.
-
Tidy Mounding Habit: Forms a dense, symmetrical clump that remains "picture-perfect" without flopping or losing its shape.
-
Pale Lavender Blooms: Produces elegant, bell-shaped flowers in midsummer that rise neatly above the high-contrast canopy.

Grower's Tip
To maintain the "frosty" blue-green centre and achieve the brightest white margins, we recommend a location with dappled morning light; avoid the parching 2:00 PM sun to prevent the waxy blue coating from melting. Because of its thick substance, 'Autumn Frost' is incredibly reliable across all Canadian zones. At our nursery in Bécancour, QC, we wait for the signature wide-margin definition and heavy leaf texture to manifest before we approve them for shipping. This True to Type verification ensures you receive a vigorous, verified plant that is ready to bring a touch of seasonal brilliance to your landscape.
