Care
Watering
Water moderately during the growing period, especially if rainfall is lacking. This plant tolerates drought well once established. Avoid excess moisture, which promotes root rot.
Light exposure
Place your densely-flowered pepperweed in full sun for optimal growth. It also accepts partial shade, but will flower more abundantly with at least 6 hours of direct sunlight daily.
Pruning and cutting
Light pruning after flowering encourages branching and maintains a compact form. Remove spent flowers and dry stems to stimulate new growth. Generally undemanding when it comes to pruning.
Soil
Choose well-draining soil, poor to moderately fertile. This species adapts to rocky or sandy terrain. Avoid overly compacted or waterlogged soils.
Fertilizing
Apply a balanced fertilizer once or twice at the start of the growing season. Poor soil is often sufficient for this hardy plant; excess nitrogen promotes foliage at the expense of flowering.
Diseases and pests
Generally resistant, it may occasionally suffer from aphids or whiteflies. Good drainage prevents most fungal diseases. Watch out especially for excess moisture in winter.
Did you know?
Densely-flowered pepperweed is a species once known for its traditional use in North America, where indigenous peoples used it as both a food and medicinal plant. Its genus name, Lepidium, comes from ancient Greek and literally means 'small scale', referring to the particular shape of its siliques (fruits).
Where to buy it
Plant in spring or early autumn, avoiding spells of intense heat. Pick a plant with healthy foliage and roots that are not exposed. Best time: March, April, May, September.
