These lilies are of the Family Liliaceae, hybrid lily, grow well in zone 3-9, on moist, humus-rich soil.
I planted the lilies next to the thuja, and they look beautifully against the golden background of the thujas. There is partial shade, sun in the morning. Their height is about 1 meter. 'Chameleon' lilies bloomed for two weeks.
All Martagon lilies are gorgeous with their numerous flowers, natural appearance, self-supporting stems, hardy growth and shade tolerance. (Wiki)
