About
Hesperis matronalis is an herbaceous flowering plant species in the family Brassicaceae. It has numerous common names, including dame's rocket, damask-violet, dame's-violet, dames-wort, dame's gilliflower, night-scented gilliflower, queen's gilliflower, rogue's gilliflower, sweet rocket, and mother-of-the-evening.
These plants are biennials or short-lived perennials, native to Eurasia and cultivated in many other areas of the world for their attractive, spring-blooming flowers. In some of those areas, it has escaped from cultivation and become a weed species. The genus name Hesperis was probably given because the scent of the flowers becomes more conspicuous towards evening (Hespera is the Greek word for evening).
How to grow it
Hesperis matronalis has been a cultivated species for a long time, and grows best in full sun to partial shade where soils are moist with good drainage. It is undemanding and self-seeds quickly, forming dense stands. Extensive monotypic stands of dame's rocket are visible from great distances; these dense collections of plants have the potential to crowd out native species when growing outside of cultivated areas.
The successful spread of dame's rocket in North America is attributed to its prolific seed production and because the seeds are often included in prepackaged "wildflower seed" mixes sold for "naturalizing". The plants typically produce a low-lying rosette of foliage the first year; in subsequent years, blooming and seed production occurs in tandem throughout the blooming season. This species is commonly found in roadside ditches, dumps and in open woodland settings, where it is noticed when in bloom. Although it makes an attractive, hardy garden plant, it has been found to be ecologically invasive in North America.
Where it grows
Hesperis matronalis is native to southern Europe from Spain to Turkey, and has been introduced to many other parts of the world with temperate climates. H. matronalis is found in many areas of Ireland, including Belfast, as a garden escape.
Uses
Young leaves are high in vitamin C, slightly bitter, and can be eaten in salads or cooked. They are available in the winter months in temperate climates, when few other greens are available. The tender shoots of the plant during the spring-time, when cooked, are considered an excellent vegetable. The flower buds are eaten as well, and the flowers used for their spicy flavor and bright color. Additionally, the seeds of the plant can be sprouted and eaten in salads.
