About this plant
Hosta 'Canadian Blue' is a shade-loving perennial known for its powdery blue foliage that maintains its cool-toned hue throughout the growing season. Its broad, heart-shaped leaves have a slightly corrugated texture, adding depth and dimension to the garden. In mid to late summer, tall flower stalks emerge, producing pale lavender blooms that attract pollinators.
'Canadian Blue' retains its blue tones longer than many other blue-leaved hostas, even in warmer climates where some varieties tend to fade to green. Its thick leaves provide better resistance to slugs, making it a durable choice for woodland gardens and shaded borders. With its cool-toned foliage and elegant summer blooms, this hosta adds a calming presence to any landscape.

Design tip
The long summer show pairs well with plants that peak earlier, keeping one area interesting for months. Keep it out of hot afternoon sun and layer it with woodland companions for a full, settled look.
