A Stately Sapphire Sentry for the Modern Garden
A 2009 introduction from world-renowned hybridizer Bob Solberg of Green Hill Farm, Hosta 'Blue Ridge' is a massive, all-blue sport of the famous Hosta 'Frost Giant'. This cultivar quickly establishes itself as a towering, upright presence — a pinnacle of structural design for any shaded landscape. Whether you are gardening in the humid expanses of Ontario or the rugged terrain of the Maritimes, its ability to maintain a rich, blue-green hue through the heat of late summer makes it a reliable standout among large-scale perennials.
Why It Stands Out
-
Luminous Glaucous Foliage: The thick, slightly rippled leaves emerge with a heavy sapphire-blue wax in spring, transitioning to a deep, sophisticated blue-green as the season matures.
-
Sturdy Upright Architecture: Massive leaves are held aloft by strong, vertical petioles, creating an impressive vase-like mound — an excellent backdrop for smaller "Mouse Ears" or hosta rarities.
-
Summer Floral Display: In early summer, straight scapes rise above the blue canopy to present clusters of near-white flowers, adding a bright flicker of contrast to the cool tones of the plant.
-
Exceptional Heat Tolerance: Uniquely bred to hold its composure better than most large blues, it is a hallmark of vigour that thrives even in warmer southern micro-climates or exposed northern sites.

Grower's Tip
Give this giant plenty of room to breathe — its wide-reaching spread can easily overlap smaller neighbours as it reaches maturity. We follow a strict True to Type verification process in our Bécancour fields, ensuring the upright habit and waxy blue coating of the 'Frost Giant' lineage are perfectly represented before we ever pack a division for you.
