A Glacial Burst of Low-Profile Elegance
Hosta 'Avalanche' is a refined registered seedling of 'Warwick Choice', brought to the horticultural world by originator Randy Goodwin in 2000. Perfectly suited for the front of a Canadian border or a specialized rock garden, this small-category selection offers a sophisticated silhouette that belies its hardy nature. The ovate leaves are defined by a deep, forest-green centre and a striking, crisp white edge that remains sharp from the melting snows of April through the humid peak of August. Its compact mounding habit makes it a premier choice for gardeners seeking high-impact variegation in tighter spaces without sacrificing the classic hosta form.
Why It Stands Out
-
Sharp Edge Variegation: Features wide, clean white margins that provide a dramatic contrast against the dark green leaf blades.
-
Bell-Shaped Blooms: Produces elegant, near-white flowers on 45 cm green scapes that hover perfectly above the foliage.
-
Compact Architecture: Reaches a tidy 33 cm height, making it an excellent "filler" or "edger" for structured shade beds.
-
Textured Ovate Leaves: The rounded leaf bases and 6–8 deep vein pairs add a sense of rhythmic texture to the garden floor.

Grower's Tip
Because Hosta 'Avalanche' is a smaller variety, its spring emergence is a critical time to observe its health and the clarity of its white margins. At our Bécancour facility, we monitor these small-scale perennials closely to ensure every division is True to Type before it leaves our care. For the best display from BC to Newfoundland, plant in moisture-retentive soil to keep the white edges from scorching during dry spells.
Note: The picture provided shows spring colouring before the margin goes white.
