A Stout Sapphire Sentry for the Canadian Shade
Masterfully introduced by the legendary Bob Savory of Savory's Gardens, Hosta 'Blue Troll' is a rugged, mid-sized performer that lives up to its mythical name. This variety is a hallmark of durability, forming a dense, ground-hugging mound that thrives from the rocky terrains of the Canadian Shield to the lush gardens of the Niagara Peninsula. Its compact but expansive habit makes it a reliable choice for those seeking a no-fuss blue that maintains its composure against the unpredictable shifts of our northern seasons.
Why It Stands Out
-
Intense Cobalt Foliage: The thick, heart-shaped leaves are cloaked in a heavy glaucous bloom, providing a deep, matte sapphire tone that remains a standout through the summer heat.
-
Rugged Leaf Substance: With a leathery texture and prominent veining, this cultivar offers exceptional slug resistance, ensuring the foliage stays pristine from spring emergence to autumn frost.
-
Compact Architectural Form: Growing into a wide, low-slung mound, its ground-hugging profile is ideal for edging a woodland path or anchoring a shady rockery — and acts as a natural weed suppressant once established.
-
Delicate Summer Contrast: In midsummer, sturdy scapes bear clusters of soft lavender flowers, providing a gentle vertical flicker against the dense, blue-green canopy.

Grower's Tip
Because Hosta 'Blue Troll' is so low-growing and dense, it acts as an excellent natural weed suppressant once established. To ensure your garden receives that signature toughness and deep blue hue, we strictly observe every plant in our Bécancour fields to verify it is True to Type before it is ever cleared for shipping.
