Variety description

10 August 2026

The plant belongs to the category of medium hostas, reaching 40–60 cm in height and 90–100 cm in width. The leaf blades are distinguished by high density and heavy texture, possess slight undulation, and maintain their contrasting coloration throughout the entire season.

Flowering occurs in mid-summer, from July to August. The plant forms tall scapes up to 90–120 cm, upon which light lavender flowers bloom. The variety is characterized as relatively slow-growing, possessing a good upright bush form that is resistant to lodging.

Due to the thickness of the leaf blade, the variety exhibits increased resistance to diseases, in particular to Verticillium wilt, and higher tolerance to sunlight compared to the parent variety. The hosta is also resistant to air pollution and is well-suited for planting in partial shade and shade.
