Hesperis matronalis

Hesperis matronalis, or Dame's Rocket, is a perennial plant with a rosette habit. Its main asset is its powerful fragrance reminiscent of jasmine. The name Hesperis comes from the Greek word hespera, meaning "evening", alluding to the stronger scent of the flowers in late afternoon. Insects are attracted to this flower. The flowering starts at the end of May and lasts until July. Impressive pink-lilac flowers with a diameter of 2cm (1in) appear in clusters.

It is a very hardy plant as long as the soil is well-drained. This allows it to be cultivated without any issues in many regions. It has a rapid growth rate from the first year. It does not live for a long time but self-seeds abundantly. Its stems bear dark green deciduous lanceolate leaves, 10 to 25cm (4 to 10in) long.

Native to southern Europe, Siberia, and western and central Asia, it can grow from 60cm (24in) up to 1m (3ft) in height. It is often placed in flower beds near houses to enjoy its sweet fragrance. It is also suitable for wild gardens as it self-seeds freely. The variety pairs well with pale-blue or violet delphiniums, as well as bright yellow rudbeckias. It can be combined with pure white panicle phlox, white bee balms, summer daisies, or even dahlias to create a beautiful white garden.
