Sweet Rocket

Hesperis matronalis - Hesperis matronalis grows 100 cm or taller, with multiple upright hairy stems. Typically the first year of growth produces a mound of foliage and flowering occurs the second year, plants are normally biennials but a number of races can be short lived perennials. The plants have showy blooms in early to mid spring. The leaves are alternately arranged on upright stems and lanceolate shaped, they typically have very short or lack petioles and have toothed margins but sometimes are entire, they are widest at the base. The foliage has short hairs on the top and bottom surfaces that give the leaves a somewhat rough feel. The larger leaves are around 12 cm long and over 4 cm wide. In early spring, a thick mound of low growing foliage is produced, during flowering the lower parts of the stems are generally unbranched and denuded of foliage and the top of the blooming plant might have a few branches that end in inflorescences.

The plentiful fragrant flowers are produced in large showy terminal racemes, that can be 30+ cm tall, that elongate as the flowers of the inflorescence bloom. When stems have both flowers and fruits, the weight sometimes causes the stems to bend. Each flower is large (2 cm across), with four petals. Flower coloration varies, with different shades of lavender and purple most common, but white, pink, and even some flowers with mixed colors exist in cultivated forms. A few different double-flowered varieties also exist.[2] The four Petals are clawed and hairless. The flowers have six stamens in two groups, the 4 closest to the ovary are longer than the two oppositely positioned. Stigmas are two-lobed. The four sepals are erect and form a mock tube around the claws of the petals and are also colored similarly to the petals.
