Hosta Flemish Angel will form a substantial mound, reaching approximately 30cm to 45cm in height, with a spread of up to 100cm at full maturity. Classified as a giant, its large blue-green leaves feature a pale-yellow border in the spring, which transitions to a wider white margin later in the season. The leaves are broadly ovate with a cordate base, moderately flat, and dull on the upper surface. Hosta Flemish Angel can tolerate significant morning sunlight without exhibiting signs of burning. In June and July, it produces white flowers that rise well above the foliage on scapes up to 75cm tall. This variety is both sun-tolerant and resistant to slugs.
