Uses and Benefits: Hosta 'Halcyon' is a beloved selection for adding cooling contrast and calm structure to shaded borders, underplantings, and woodland designs. Its bold blue foliage pairs effortlessly with silver, chartreuse, and green companions. Tolerant of dry shade once established, it’s a staple for creating sophisticated, low-maintenance combinations that mature gracefully over time.

Companion Plants: Pair Hosta 'Halcyon' with Brunnera 'Silver Heart', whose luminous leaves echo the hosta’s cool tones and brighten dim corners. Add Polystichum 'Tassel Fern' for arching, deeply cut fronds that bring textural contrast. Soften the composition with the flowing blades of Hakonechloa macra, which add movement and depth without overpowering the hosta’s structure.

Care Instructions: Grow in partial to full shade in moist, well-drained soil with plenty of organic matter. Protect from strong afternoon sun to maintain the blue hue. Water regularly during hot spells, and clean up old foliage in early spring. Divide every 4–5 years to rejuvenate and maintain clump size.

History: Hosta 'Halcyon' is part of the renowned Tardiana group, developed by British breeder Eric Smith in the mid-20th century. Known for its long-lasting blue colour and excellent substance, it remains one of the most trusted blue-leaved hostas in cultivation.

Final Thoughts: A garden essential for shade, Hosta 'Halcyon' brings quiet strength and enduring beauty—its cool, sculptural leaves a balm for bright summer borders and shady sanctuaries alike.
