Hosta Night Before Christmas is a medium-sized, clump-forming herbaceous perennial that develops a broad mound about 40 to 45 cm high and 85 to 90 cm wide. Large, narrow heart-shaped leaves arch outward from the crown. Each leaf has a wide dark green margin surrounding an irregular cream centre that becomes clearer white by summer, often with brush-like transitions between the colours. Tall scapes rise above the foliage in mid to late summer and carry loose racemes of nodding pale lavender, funnel-shaped flowers. The plant is grown mainly for its bold variegated leaves and architectural shade-garden presence.
Grow Night Before Christmas in partial or full shade in fertile, humus-rich soil that stays evenly moist while draining freely. Shelter leaves from persistent drying wind and harsh direct sun, which can scorch the pale centres. Apply a light organic mulch in spring without burying the crown, and water deeply during dry spells. Divide vigorous clumps in spring or late summer. Remove spent scapes and clear collapsed foliage during dormancy. Slugs, snails, deer, and vine weevil grubs are the main pests. Hosta virus diseases, leaf spots, and crown or root rots are possible where hygiene, airflow, or drainage is poor. The plant is toxic to dogs, cats, and horses if eaten.
