Dame's Rocket Hesperis matronalis
ABOUT
Hesperis matronalis, commonly known as dame's rocket, is a flowering plant with an attractive appearance that has made it popular in gardens. The plant features a basal rosette of leaves from which upright stems emerge. These stems are adorned with lance-shaped leaves that are toothed along the edges. The leaves further up on the stems are alternately arranged and become smaller as they ascend the stem. The dame's rocket is well-known for its showy flower clusters that come in shades of white, pink, purple, and sometimes violet. Each flower consists of four cross-shaped petals, forming a simple yet charming floral display. The blossoms typically have a delightful fragrance, especially noticeable in the evening. After flowering, the plant produces elongated seed pods that split open when mature, dispersing the seeds inside. The overall visual appeal of dame's rocket is enhanced by its lush foliage and the clustered effect of its blooms, which can add a wildflower-like charm to any planting area where it is present.

During hot or dry periods, increase the frequency to twice a week, providing up to 1.5 gallons per watering for an average-sized plant. In cooler or rainy spells, reduce the watering to every 10 to 14 days, always checking the soil moisture before watering to avoid over-saturation.
LightDame's Rocket thrives in full sun to partial shade, so the best spot for it would be where it can receive at least 6 hours of direct sunlight a day. It can tolerate some shade, especially in the afternoon, which can help protect it from the heat of the day in hotter climates.
TemperatureDame's Rocket is hardy and can survive in temperatures as low as 40°F. It performs best when grown in temperatures ranging from 60°F to 70°F. Extreme heat above 85°F might stress the plant, so providing some shade during the hottest part of the day is beneficial.
PruningPrune Dame's Rocket after it has finished flowering to encourage a second bloom and to prevent self-seeding if desired. Cut back the spent flower stalks to the base of the plant. Pruning should be done yearly, typically in the late spring or early summer following the bloom period.
CleaningAs needed
SoilDame's Rocket prefers a well-draining soil rich in organic matter with a pH range of 6.0 to 7.5. A good mix would be equal parts loam, peat, and sharp sand to ensure adequate drainage and fertility. Mulch can be added to help retain moisture.
RepottingDame's Rocket, being a biennial or short-lived perennial plant, does not typically require frequent repotting. It can be repotted or transplanted when it has outgrown its current container or if the soil has become exhausted, roughly every 2-3 years.
Humidity & MistingDame's Rocket is tolerant of a wide range of humidity levels and does not require any specific humidity requirements to thrive. Ambient outdoor humidity is generally sufficient for its growth.

Life cycleDame's rocket (Hesperis matronalis) begins its life cycle when seeds germinate in early spring, usually requiring chilling through winter to break dormancy. Once germinated, the seedlings grow into a basal rosette of leaves that remain close to the ground during their first year, establishing a strong root system. In its second year, the plant bolts, sending up tall flowering stalks that can reach up to 4 feet in height, with leaves becoming more sparse along the stem. From late spring to early summer, Dame's rocket produces showy clusters of fragrant flowers, typically four-petaled and ranging in color from purple to pink and white. After flowering, the plant produces seed pods that eventually split open to disperse seeds, which can be spread by wind or water. The adult plant usually dies after seed production, completing its biennial life cycle, though some plants can behave as short-lived perennials.
PropogationPropogation time
Spring to early summer
The most popular method to propagate Dame's Rocket, scientifically known as Hesperis matronalis, is through seed sowing. Dame's Rocket seeds can be directly sown into the garden after the threat of frost has passed in late spring. Alternatively, the seeds can be started indoors 6-8 weeks before the last expected frost. Scatter the seeds on the surface of the soil and press them in lightly, as they require light for germination. Keep the soil moist but not waterlogged until seedlings emerge, which usually takes about 10-21 days. After seedlings have developed a couple of sets of true leaves, they can be thinned and transplanted outdoors, spacing them about 15 to 18 inches (roughly 38 to 46 centimeters) apart to allow ample room for growth.
