A Shimmering Cerulean Waterfall for Your Canadian Garden
Emerging from the creative minds of M. & J. Carlson, Hosta 'Blue Cascade' is a low-growing, wide-reaching marvel that brings a sense of fluid motion to your shade borders. By crossing a white-backed H. longipes var. latifolia with the legendary Hosta 'Elvis Lives', the hybridizers captured a unique architectural form where twisted leaf tips mimic the spray of a mountain stream. Whether you are gardening in the humid Maritimes or the crisp air of the Rockies, this cultivar holds its intense, glaucous bloom with remarkable vigour throughout our short but intense Canadian summers.
Why It Stands Out
-
Persistent Cobalt Hue: Unlike many blues that fade to green by July, this variety maintains its waxy, sapphire coating well into the autumn.
-
Dynamic Texture: The ovate leaves feature heavily rippled margins and a light corrugation that catches the low-angled northern sun.
-
Striking Floral Contrast: In late summer, vibrant purple scapes rise above the mound to display deep purple, tubular flowers with delicate lavender striping.
-
Architectural Interest: The cascading effect is amplified by the way the leaves twist and wave, creating a sense of depth and movement in the garden.

Grower's Tip
To truly appreciate the cascade in Hosta 'Blue Cascade', plant it atop a slight slope or in a raised stone bed where the twisted tips can spill over the edge. Because we are committed to shipping only True to Type specimens, we wait for the first signs of those rippled margins and deep blue waxy coating to emerge in our Bécancour fields before we ever pack a box for you.
