General Description

Looking like wild mustard or wild radish, the garden yellowrocket bears small cross-shaped yellow flowers from early spring to early summer. This biennial or very short-lived perennial typically grows in the cooler months, from autumn to spring, becoming dormant in the heat of summer.

The long taproot supports a rosette of medium green leaves that are elongated with lobes. The flower stem arises from the center of this rosettes and branches many times to support scores of tiny lemon yellow blossoms that will attract butterflies. After producing seeds, the plant dies. Sprouting seedlings focus on growing leaves and roots the first growing season, and then produce the flowers in the second.

Sow the seeds of garden yellowrocket wear the plants are to grow and allow them to immediately germinate in a moist, well-draining soil. They grow well in full sun to partially shaded location. Once introduced into the garden, plants will reseed themselves and the location of flwoering plants migrates around. Use garden yellorocket as an ornamental flower in the front of the flower border, intermingled with spring flowering bulbs or perennials. Cultivar 'Variegata' produces leaves that are edged in yellow. Some gardeners regard garden yellowrocket as an annoying but pretty flowering weed in lawns or meadow pastures.
