Hosta Halcyon brings a clean blue foliage effect to shaded garden spaces. Spear-shaped blue-green leaves gather into a reliable rounded clump that fits woodland-style borders and patio containers. Purple bell flowers rise above the foliage in summer. The simple leaf color makes an easy background for silver, gold, or flowering shade companions.
Grow it in partial, full, or light shade and keep the ground consistently moist but well drained. Add compost around the crown in spring and avoid heavy fertilizer that creates soft leaves. Remove faded flower stems after bloom and clear collapsed foliage in late fall or early spring. Divide as new shoots emerge in spring. Slugs and snails may damage the leaves, and the plant is toxic to dogs, cats, and horses if eaten.
