Plant Overview
Streptanthus barbiger, commonly known as the bearded streptanthus, is a flowering plant belonging to the Brassicaceae family, which includes a variety of well-known plants such as cabbage and mustard. This species is endemic to California, particularly found in the Sierra Nevada foothills. Here are some detailed characteristics and information about Streptanthus barbiger:
Morphology:
- Growth Habit: Streptanthus barbiger is a perennial herb that typically grows upright, reaching heights of up to 30 cm (about 1 foot).
- Leaves: The leaves are lanceolate or oval, with a glossy surface. They are arranged in a rosette at the base and can be serrated or entire.
- Flowers: The plant produces delicate, tubular flowers that are usually purple to lavender in color, with a distinctive bearded appearance, hence the common name. The flowers are arranged in racemes, meaning they grow along a central stem in a branched manner.
Habitat:
- Distribution: This species is primarily found in the chaparral and woodland habitats of California, particularly at elevations ranging from 300 to 1200 meters.
- Soil Preference: It typically thrives in rocky, well-drained soils and is often found in areas with some disturbance, which may help reduce competition from other plant species.
Reproduction:
- Pollination: The bearded streptanthus relies on insect pollinators, including bees, for reproduction. The structure of the flowers is adapted to attract and facilitate the access of these pollinators.
- Seed Production: After flowering, the plant produces elongated seed pods that can release seeds into the surrounding soil, aiding in species propagation.
Conservation Status:
- Threats: The primary threats to Streptanthus barbiger include habitat loss due to urban development, agricultural expansion, and invasive species. As a result, its populations may be fragmented and vulnerable.
- Conservation Efforts: Various conservation programs aim to preserve its natural habitat and promote the growth of native plants in the regions where it is found.
Uses:
- Ecological Role: Streptanthus barbiger plays a role in its ecosystem by providing nectar for pollinators and contributing to soil stability with its root system.
- Cultural Significance: While not widely used in horticulture, some native plant enthusiasts value it for its unique appearance and role in local biodiversity.
In summary, Streptanthus barbiger is a distinctive California native plant that contributes to its local ecosystems. Its unique features and specific habitat requirements make it an important species for conservation efforts and for those interested in native plant gardening.

Detailed Care Instructions
To grow Streptanthus barbiger, also known as the Bearded Jewelflower, follow the steps below:
- Climate and soil: Streptanthus barbiger is a native plant to California and prefers a Mediterranean climate. It thrives in well-draining soil with a slightly acidic to neutral pH. If you live in a different climate, you can try to recreate the conditions by providing adequate sunlight, moisture, and temperature.
- Starting indoors: Start the seeds indoors about 6-8 weeks before the last expected frost. Sow the seeds on top of a seed-starting mix and cover them lightly. Keep the soil consistently moist and maintain a temperature of around 65-70°F (18-21°C). Germination can take 1-2 weeks.
- Transplanting: Once the seedlings have developed true leaves and the risk of frost has passed, you can transplant them outdoors. Choose a location with full sun or partial shade, depending on your climate. Make sure the soil is well-draining and prepared by working in some compost.
- Planting: Dig a hole slightly larger than the root ball of the seedling. Gently remove the seedling from its container and place it in the hole, making sure the soil level matches that of the container or slightly lower. Backfill the hole and gently tamp down the soil around the plant to remove any air pockets.
- Watering: Streptanthus barbiger requires regular watering, especially during dry periods. Keep the soil consistently moist but not waterlogged. Avoid overhead watering to prevent foliage diseases; instead, water at the base of the plant.
- Mulching and maintenance: Apply a layer of organic mulch around the plant to help retain moisture, control weeds, and regulate soil temperature. Remove any weeds that emerge around the plant to avoid competition for nutrients and water.
- Fertilizing: Streptanthus barbiger is adapted to low-nutrient environments, so it generally does not require much fertilization. However, you can apply a slow-release, balanced fertilizer once in early spring to encourage healthy growth.
- Pruning and deadheading: To keep the plant compact and encourage additional blooms, you can pinch off the spent flowers. Additionally, you can trim back the plant after the blooming season to maintain its shape and encourage new growth.
- Pests and diseases: Streptanthus barbiger is generally pest and disease resistant. However, keep an eye out for any signs of disease or infestation, such as yellowing leaves or distorted growth, and take the necessary steps to address them promptly.
It's worth noting that Streptanthus barbiger may have specific requirements depending on your location and climate. It's always recommended to consult with your local gardening center or extension service for region-specific advice.
Place in a bright room that is sun drenched almost all day. Or directly in a south-facing window.
To properly water this plant, it is important to take into consideration the soil moisture condition. Water should be given when the top inch of soil is dry to the touch. When watering, make sure to water slowly and deeply to ensure that the root system is getting enough water. Adequate drainage is also important to prevent overwatering. Avoid spraying water directly on the leaves or flowers to prevent damage. During the colder months, reduce watering frequency as the plant goes into a dormant state.
To fertilize this plant, you should use a balanced fertilizer with a ratio of 10-10-10. Apply the fertilizer at half strength every two weeks during the growing season, which typically lasts from spring to early summer. Be careful not to over-fertilize as it can harm the plant. Additionally, make sure to water the plant well before and after fertilizing.
Streptanthus Barbiger plant prefers soil with good drainage and moderate fertility. It grows well in sandy or loamy soil with a slightly acidic to neutral pH. The soil should be well-aerated to prevent waterlogging, as this may lead to root rot. Adding organic matter, such as compost or aged manure, to the soil before planting can improve fertility and soil structure. Additionally, mulching around the plant can help retain moisture and suppress weed growth. It is important to ensure that the soil is not too compacted, as this can inhibit root growth and nutrient uptake.
Propagation of this plant can be done through seedlings or by stem cuttings. For seed propagation, it is important to collect the mature seed pods and allow them to dry completely before extracting the seeds. They should then be sown in a suitable potting mix and kept in a warm and well-lit area. Regular watering is necessary to ensure optimal growth.
Stem cuttings can also be taken from the plant for propagation. Cuttings should be taken from the mature stems of the plant and dipped in rooting hormone before being planted in a moist potting mix. The cutting should be kept in a warm and humid environment until it has developed a root system and new growth appears.
In both cases, it is important to keep the plant well-watered and protected from harsh sunlight until it becomes established. Once the plant is established, it can be transplanted to its permanent location in the garden.
