Appearance
Scrophularia plants are typically herbaceous perennials that can grow up to 1.5 meters tall. The stems are often square-shaped and hairy. The leaves are opposite, with toothed margins and a pointed tip. The flowers are usually arranged in a loose, branching cluster and can be green, brown, or purple. The fruit is a fig-shaped capsule, which contains numerous seeds.
Care Guide
Scrophularia plants prefer a moist, well-draining soil that is rich in organic matter. They also require full sun to partial shade and thrive in hardiness zones 4 to 8. These plants should be watered regularly, but care should be taken not to overwater as this can lead to root rot. Fertilization should be done with a balanced fertilizer in the spring, and mulching can help to retain moisture in the soil.
Common Pests & Diseases
Scrophularia plants are relatively resistant to pests and diseases. However, they may be susceptible to powdery mildew, which can be prevented by ensuring adequate air circulation and avoiding overhead watering. Spider mites may also infest these plants, which can be controlled with insecticidal soap or neem oil.
Habitat
Scrophularia plants are commonly found in moist habitats, such as woodland edges, riverbanks, and meadows. They are native to the Northern Hemisphere and are distributed across Europe, Asia, and North America.
