Hesperis matronalis

Hesperis matronalis, commonly known as Dame's Rocket, is a short-lived perennial or biennial plant often grown for its fragrant flowers. It typically reaches a height of 2 to 4 feet. The plant features lance-shaped, toothed leaves and produces clusters of four-petaled flowers in shades of purple, pink, or white. The flowers are particularly fragrant in the evening, hence the name 'Mother-of-the-Evening'. While it can be grown from seed easily, it is considered invasive in some regions of North America due to its aggressive self-seeding. It is primarily an outdoor plant, valued for its showy blooms and evening fragrance in gardens and naturalized areas.

Fertilizing Balanced fertilizer (10-10-10) in spring
Seasonal Care In spring, fertilize and monitor for pests. In summer, water regularly. In fall, collect seeds or allow self-seeding. In winter, the plant may die back and re-emerge in spring.

Night Blooming Cereus

Repotting Every 2-3 years, or when the plant becomes root-bound.
Pruning Prune to control size and shape, removing any dead or damaged stems. Best done after flowering.
Fertilizing Balanced liquid fertilizer diluted to half strength, applied monthly during the growing season (spring and summer).
Seasonal Care In summer, provide ample sunlight and water when the soil is dry. In winter, reduce watering and provide cooler temperatures to encourage dormancy and future flowering.
