It grows well in moist, slightly acidic soils, in locations sheltered from the wind, slightly shaded. It does not require an annual cut, only a cosmetic cut should be applied in spring. Moderate frost resistance, young plants should be covered for the winter. The variety is recommended for home gardens, parks and urban greenery. It looks impressive when planted in groups.
