A Cascading Wave of Rippled Blue
Hosta 'Waterslide' is a breathtaking addition to the Walters Gardens "Shadowland" collection, specifically engineered to bring a sense of fluid motion to your shade garden. This medium-sized powerhouse is celebrated for its incredibly wavy, ruffled leaf margins that mimic the churning water of a mountain stream. The foliage is heavy and leathery, draped in a thick, glaucous wax that provides one of the most persistent blue colours available to gardeners today. Whether planted as a solitary specimen or in a flowing mass, 'Waterslide' maintains its "splashing" architectural form from its spring emergence in Bécancour right through the heat of a humid July.
Why It Stands Out
-
Extreme Pie-Crust Ruffling: The intensely wavy margins create a dynamic, layered look that adds incredible texture and movement to the border.
-
Steadfast Blue Coating: Features a heavy waxy bloom that keeps the leaves a cool, frosty blue long after other varieties have transitioned to green.
-
Superior Slug Resistance: The thick, "alligator-skin" substance makes this variety a difficult target for pests, ensuring the ruffled edges stay pristine.
-
Unique Pointed Tips: Long, lance-shaped leaves with sharp tips draw the eye downward, enhancing the "cascading" effect of the mound.
-
Lavender Summer Interest: Topped with tall, sturdy scapes of lavender flowers in late summer, providing a soft vertical contrast to the blue waves.

Grower's Tip
To preserve the "frosty" blue wax that makes 'Waterslide' so spectacular, we recommend a location with deep or dappled shade; excessive direct sunlight can melt the wax and reveal the green leaf beneath. This variety loves a moisture-retentive soil to support its thick, ruffled foliage. At our nursery in Bécancour, QC, we wait for the signature "wiggle" in the leaf margins and the deep blue saturation to manifest before shipping. This True to Type verification ensures you receive a vigorous, verified plant that is ready to make a splash in your local landscape.
