Common Names
The Glandular Jewel Flower has several common names including, Western jewelflower, Sticky class jewelflower, and Sticky Streptanthus.
Uses
Streptanthus glandulosus Hook. ssp. secundus (Greene) Kruckeberg has a few medicinal uses, as some Native American tribes have used the plant to treat issues, such as diarrhea and sore throats. However, it is mostly valued as an ornamental plant used for landscaping purposes, especially as an addition to rock gardens.
General Appearance
The Glandular Jewel Flower grows as an upright plant with green, elongated, and sticky leaves growing to a length of 7-12 cm. The flowers are a beautiful bright yellow, with four petal-like sepals that bloom from February to June. Each flower grows up to 3 cm in diameter. This plant can grow up to 60 cm tall and typically grows in a moist and rocky environment.
Light Requirements
The Streptanthus glandulosus Hook. ssp. secundus (Greene) Kruckeberg plant requires full sunlight exposure for proper growth and development. Without ample exposure to sunlight, the plant may not produce sufficient flowers or achieve its full potential in terms of size and overall vigor.
Temperature Requirements
The Streptanthus glandulosus Hook. ssp. secundus (Greene) Kruckeberg plant is best suited to grow in regions with moderate to cool temperatures. Ideal temperatures for the plant range between 60 and 75°F (15 and 24°C). These temperatures provide the plant with the necessary conditions to thrive and reach maturity.
Soil Requirements
The Streptanthus glandulosus Hook. ssp. secundus (Greene) Kruckeberg plant is best grown in soil with good drainage capacity and moderate organic matter content. The soil should have a pH between 6.0 and 7.5 to ensure optimal growth and nutrient uptake. The plant can grow in rocky or sandy soils but may require regular watering to maintain proper moisture levels. It is also important to note that the plant should not be grown in soils with a heavy clay content.
Cultivation methods for Streptanthus glandulosus Hook. ssp. secundus (Greene) Kruckeberg
Streptanthus glandulosus Hook. ssp. secundus (Greene) Kruckeberg prefers to grow in well-draining, sandy or loamy soil. The plant can tolerate acidic or alkaline soil, but it thrives best in neutral or slightly acidic soil pH. For successful cultivation, select a site with full sun exposure. If grown in partial shade, the plant may produce fewer flowers.
Watering needs for Streptanthus glandulosus Hook. ssp. secundus (Greene) Kruckeberg
Streptanthus glandulosus Hook. ssp. secundus (Greene) Kruckeberg has moderate water requirements. Water the plant thoroughly once a week during the growing season. Ensure that the soil remains evenly moist but not waterlogged. The plant can tolerate brief periods of drought, but prolonged water stress can cause stunted growth and reduced flowering.
Fertilization for Streptanthus glandulosus Hook. ssp. secundus (Greene) Kruckeberg
Streptanthus glandulosus Hook. ssp. secundus (Greene) Kruckeberg is not a heavy feeder. Apply a balanced fertilizer once in early spring and another application in midsummer. Use a slow-release granular fertilizer, or dilute a water-soluble fertilizer to half strength. Avoid overfertilizing, as this can lead to excessive vegetative growth and reduced flowering.
Pruning for Streptanthus glandulosus Hook. ssp. secundus (Greene) Kruckeberg
Streptanthus glandulosus Hook. ssp. secundus (Greene) Kruckeberg requires minimal pruning. Remove any dead, damaged, or diseased branches as soon as they appear. This helps to maintain the plant's overall health and appearance. After flowering, you can deadhead the plant to promote additional blooming and to prevent self-seeding. Use sharp pruning shears to make clean cuts, and disinfect the blades between cuts to prevent the spread of diseases.
Propagation of Streptanthus glandulosus Hook. ssp. secundus (Greene) Kruckeberg
Streptanthus glandulosus Hook. ssp. secundus (Greene) Kruckeberg, commonly known as “glandular jewel-flower”, is a species of flowering plant that is endemic to California, USA. It grows well in full sun to partial shade and prefers well-drained soils with sandy or gravelly textures. Propagation of this species is possible through the following methods:
Seed Propagation
Propagation of Streptanthus glandulosus Hook. ssp. secundus can be achieved through seed propagation. Collect the seeds after the pods have turned brown and dry on the plant. The seeds should be cleaned and stored in a cool, dry place, out of direct sunlight. Germination is often enhanced by treating the seeds with smoke water or a smoke solution. Sow the seeds in a well-drained seed-raising mix in a pot or seed tray. Keep the soil moist and warm, between 15-25°C (59-77°F), and place the pot or tray in a bright spot, but not in direct sunlight. The seeds should germinate within 2-4 weeks and can be transplanted into individual pots or a larger container once they have developed their first true leaves.
Cuttings Propagation
Propagation through cuttings is also possible, but this method is less commonly used. Take cuttings in the summer, and use non-flowering stems taken from the base of the plant. Dip the base of the cuttings in a rooting hormone, and plant them in a well-draining potting mix. Place the pot in a bright, warm location and keep the soil moist but not waterlogged. The cuttings should root within 4 to 6 weeks and can be transplanted into individual pots or a larger container.
Propagation of Streptanthus glandulosus Hook. ssp. secundus (Greene) Kruckeberg is possible through both seed and cuttings propagation methods, and choosing the right method depends on the grower's preferences and resources. By properly propagating the plant, you can enjoy the beauty and benefits of this wonderful flowering plant.
Disease Management
Streptanthus glandulosus Hook. ssp. secundus (Greene) Kruckeberg is generally resistant to most plant diseases. However, it can still be affected by some common plant diseases such as:
- Black spot: This fungal disease causes black spots on the leaves, which can lead to defoliation if not managed early. Infected leaves must be removed and destroyed as soon as they are noticed, and the plant must be treated with fungicide.
- Powdery mildew: This is another fungal disease that appears as white powdery substance on the leaves and stems. It can cause stunted growth and deformation in severe cases. Regular pruning, proper air circulation, and fungicide application are effective in controlling powdery mildew.
- Anthracnose: This fungal disease can cause brown spots to form on the leaves, leading to defoliation if left untreated. Fungicide application, removing infected leaves, and sterilizing pruning tools are some of the ways to manage anthracnose.
Pest Management
Streptanthus glandulosus Hook. ssp. secundus (Greene) Kruckeberg is also prone to some pest attacks, such as:
- Spider mites: These tiny pests can cause yellowing and spotting on the leaves by piercing through the leaf surface and feeding on the plant's sap. Spraying the plant with insecticidal soap or neem oil can help control spider mites.
- Aphids: These are small insects that attach themselves to the plant's leaves and suck on its sap. They can cause wilting and yellowing of the leaves. Managing aphids involves the use of natural predators like ladybugs and parasitic wasps or applying insecticidal soap.
- Slugs and snails: These pests can cause extensive damage to the plant by eating holes in the leaves and stems. Using slug baits, copper barriers, and handpicking are ways to manage slugs and snails.
Keeping the plant healthy by providing adequate water, nutrients, and sunlight also goes a long way in preventing pest and disease attacks. Regular monitoring for signs of disease and pest infestation is also necessary for early detection and effective management.
