About
This tuberous perennial reaches a height of 50 cm and forms a dense clump of deeply lobed, green leaves. From mid-summer through mid-autumn, it produces upright stems that bear solitary flowers in a deep red hue, known for their chocolate fragrance. The blooms can be found in single, double, or quilled petal forms. This variety can be propagated from seed.
