A Stately Sapphire Sentinel of Southern Pedigree
Masterfully hybridised by Bob Solberg and registered in 2000, Hosta 'Carolina Blue' is a sophisticated pinnacle of blue breeding, born from a refined cross of Hosta 'Halcyon' and Hosta 'Riptide'. This mid-sized cultivar brings a sense of cool, architectural calm to the garden, performing with a reliable, moderate growth rate that makes it a hallmark of the shade border. Its ability to maintain its glaucous complexion throughout the Canadian growing season makes it a consistent standout for collectors and casual gardeners alike.
-
Velvety Glaucous Bloom: The ovate leaves — measuring roughly 18 cm (7") long — are cloaked in a thick, waxy bloom on both the top and undersides, creating a stunning matte blue-green finish.
-
Substantial Leaf Architecture: With 8 to 9 prominent vein pairs and a classic rounded base, the foliage possesses the heavy substance necessary for exceptional slug resistance and durability.
-
Elegant Mounded Habit: Forming a dense, symmetrical 76 cm (30") wide mound, this variety stays tidy and compact, making it perfect for the mid-border or a sophisticated container.
-
Sky-High Summer Spires: Unusually tall, striking blue scapes — rising up to 81 cm (32") — emerge in summer to display clusters of pale lavender, tubular flowers high above the foliage.

Grower's Tip: The exceptionally tall scapes on 'Carolina Blue' mean you can enjoy the pale lavender blooms without them being hidden by the leaves. At our nursery in Bécancour, we strictly adhere to our True to Type mandate, monitoring the stability of the glaucous coating and the vigour of the 'Halcyon' parentage in our trial beds before your division is cleared for shipping.
