Hosta Hi-Class will develop into a medium-sized mound measuring 45cm-55cm in height and extending up to 95cm in width at maturity. This variety features exceptionally thick leaves that cup slightly and possess a smooth surface. The deep green foliage displays a blue tint during the spring and is bordered by a wide, prominent margin. Resembling a larger Hosta El Nino, Hosta Hi-Class forms an elegant, high-contrast, semi-upright clump that effectively showcases the leaves. In the summer, the leaf centres transition to dark green while the margins turn white. The plant maintains its attractive appearance until a hard frost occurs later in the year. Lavender flowers emerge on scapes reaching up to 80cm in July and continue into August. The thick leaves contribute to its resistance to slugs and tolerance to sunlight, although it thrives best in partial shade.
