Hosta (Tardiana Group) 'Halcyon' Overview

Hosta 'Halcyon' is a hardy perennial cultivar that forms compact mounds of sturdy, vivid, blue-green leaves. In mid to late summer, erect stems of nodding, bell-shaped, lavender-grey flowers appear. All Hostas need some shade, and few will thrive in strong sunlight. A general rule is that the lighter foliage, the brighter the sunlight that will be tolerated. Variegated varieties tend to require more sun to keep their white, light green or gold stripes. The darker, bluer varieties need more shade. They are ideal for growing in North facing aspects of your garden where most other plants would struggle. Once established, Hostas are pretty tough and will spread horizontally to make an excellent ground cover. They are suitable for most garden styles and look good in containers (but keep well watered and watch out for vine weevil in pots!). They require little care apart from tidying up spent leaves and flowers at the end of the growing season, preferably an autumn mulch. Also, in spring, to retain moisture. Hostas like a sheltered position in moist, well-drained soil and do best in a slightly acidic growing medium, but this isn't necessary, any good garden soil - unless very alkaline - is fine. Hosta Halcyon has earned a coveted 'RHS Award of Garden Merit'.
