Hosta Wide Brim is a medium, deciduous, rhizomatous perennial prized for bold variegated foliage. Mature leaf mounds reach about 35 to 45 cm high and spread 75 to 90 cm, while flower scapes rise to about 60 cm. Broad cordate to wide-oval leaves have cuspidate tips, rugose lightly cupped surfaces, deeply impressed parallel veins, dark green interiors with a subtle blue cast, and broad irregular margins that mature from pale yellow toward creamy white. In midsummer, tall unbranched scapes carry dense racemes of pale lavender funnel-shaped flowers. The cultivar was introduced by Paul Aden in 1979 and has long been valued in shade gardens.
Grow Wide Brim in partial or dappled shade in fertile, humus-rich acidic to neutral clay or loam that remains consistently moist but drains freely. Gentle morning light can strengthen the variegation, while strong afternoon sun and drying winds may scorch pale margins. Apply compost in spring, water deeply during dry periods, and mulch lightly without burying the crown. Divide established clumps in early spring or late summer. Slugs, snails, deer, rabbits, vine weevil, Hosta virus, foliar nematodes, and crown rot are possible problems. The plant contains saponins and is toxic to dogs, cats, and horses if eaten.
