Summary
Streptanthus glandulosus, commonly known as bristly jewelflower, is an annual herb native to the serpentine soils of chaparral, woodlands, and grasslands in California and southwestern Oregon. The plant typically grows from 4 inches to over 3 feet tall, with a variable degree of hairiness. Basal leaves are borne on winged petioles, and the flowers are distinctive with an urn-shaped calyx that can be green, purple, or yellow, with purple or white petals protruding from the tip. The fruit is a straight or curving silique that can grow up to 4 inches long.
The bristly jewelflower is appreciated for its unique floral structure and is often used in native plant gardens and restoration projects. It is adapted to serpentine soils, which are typically low in essential nutrients and high in heavy metals, making it a valuable species for habitat-specific gardening. In cultivation, it requires well-drained soils and full sun to part shade conditions. While not a common garden plant, it can be a conversation starter due to its unusual appearance and adaptation to challenging soil conditions. It is relatively low maintenance, but it can be susceptible to fungal diseases in overly moist conditions.CC BY-SA 4.0
