Variety description
10 August 2026
The plant forms a dense clump 30–60 cm tall and 60–90 cm wide. The leaves are large, up to 30 cm in length, with a silvery-white color, contrasting dark green veins, and a narrow green margin. The leaf surface is slightly wrinkled, with a metallic luster effect.
Small sky-blue flowers, resembling forget-me-nots, are gathered in loose inflorescences rising above the foliage. Flowering occurs from April to June, while the foliage retains its ornamental value until frost. The variety possesses high winter hardiness, corresponding to USDA zones 3–8.
The plant is intended for ornamental use in landscape design. It is suitable for shaded mixed borders, edgings, creating groundcover masses under trees and shrubs, as well as for decorating areas near water bodies.
