It is native to northern California and southwestern Oregon, where it inhabits rocky outcrops and forest clearings. Draba reptans has several common names, including Spreading Draba, Starflower Draba, and Native Whitlowgrass.
Appearance
Draba reptans is a low-growing plant that reaches a height of less than 6 inches. The plant produces several basal leaves that are divided into narrow, pointed lobes. The leaves are covered with tiny hairs that give them a soft texture. The flowers are small and white, with four petals arranged in a star shape. Each flower has eight stamens, which are longer than the petals. The plant blooms from late spring to early summer.
Uses
Draba reptans has some medicinal applications and is used in herbal remedies for various conditions. The plant is used to treat skin ailments, coughs, and fevers. In some cultures, it is brewed as a tea to alleviate stomach discomfort and sore throat. Additionally, some Native American tribes used the plant for its analgesic properties, applying it topically to alleviate pain.
Draba reptans is also an attractive plant for rock gardens and alpine environments. It performs well in well-draining soils and full sun to partial shade. The plant thrives in cold temperatures and can tolerate rocky, nutrient-poor soils, making it an ideal choice for xeriscape gardens or areas with low water availability.
In conclusion, Draba reptans is a versatile plant with various applications, making it a valuable addition to gardens and natural areas. With its unique appearance and medicinal benefits, it is a must-have for any gardener or herbalist.
Light Conditions
Draba reptans (Lam.) Fern. ssp. stellifera (O.E. Schulz) Abrams is a sun-loving plant that requires a minimum of 6 hours of direct sunlight per day to thrive. It can also tolerate partial shade, but too much shade can cause the plant to become leggy and weak. For optimal growth, plant in an area with full sun exposure.
Temperature conditions
The plant prefers cooler temperatures and can tolerate frost. It can be grown in USDA hardiness zones 3 to 8. Temperatures between 10 to 15°C (50 to 59°F) promotes good growth, while temperatures above 25°C (77°F) reduce growth and cause wilting of the leaves. Extreme heat can be fatal to Draba reptans (Lam.) Fern. ssp. stellifera (O.E. Schulz) Abrams plants.
Soil Requirements
Draba reptans (Lam.) Fern. ssp. stellifera (O.E. Schulz) Abrams grows best in well-drained, gravelly soil with a pH range of 6.5 to 7.5. It prefers soils that are rich in organic matter, but it doesn't tolerate soil that is too wet or too dry. It's vital to ensure good drainage as standing water can cause the roots to rot. Adding compost or leaf litter to the soil can also help to improve soil quality.
Cultivation
Draba reptans (Lam.) Fern. ssp. stellifera (O.E. Schulz) Abrams thrives in well-draining soil and in areas with full sunlight. The plant is suitable for cultivation in rock gardens, borders, and containers. To achieve optimal growth, plant in spring when the soil temperature is warm enough to sustain growth.
Watering Needs
The plant has moderate water requirements. Water deeply at least once a week, particularly during dry spells. Avoid overwatering as the plant is susceptible to root rot; instead, let the soil dry out between watering sessions. During the winter season, the plant requires less water.
Fertilization
Draba reptans (Lam.) Fern. ssp. stellifera (O.E. Schulz) Abrams does not require frequent feeding as it prefers poor, well-draining soil. If the soil is nutrient-deficient, apply a slow-release, granular fertilizer once every six weeks during the growing season. Alternatively, use a water-soluble, balanced fertilizer every three weeks.
Pruning
Draba reptans (Lam.) Fern. ssp. stellifera (O.E. Schulz) Abrams does not require pruning as it is a low-growing, ground-covering plant. However, removing spent flowers improves the plant's appearance and encourages another round of blooming. Use a sharp pair of secateurs and cut the spent flower stalk at the base. The plant recovers quickly and produces fresh foliage and new flowers shortly.
Propagation of Draba reptans ssp. stellifera
Draba reptans ssp. stellifera can be easily propagated from seeds as well as cuttings. In addition, it can also be propagated through division.
Propagation from Seeds
The seeds of Draba reptans ssp. stellifera are small and should be sown on the surface of well-draining soil mix or sandy soil. The seeds can be sown either in a seed-starting pot or directly in the ground in the fall season. The seeds require light for germination, so it is important not to cover them with soil. The ideal temperature for germination is between 50-60°F (10-15°C).
Cuttings
Draba reptans ssp. stellifera can be propagated through cuttings taken from the mother plant. Take a stem cutting in the early summer season, dip the cuttings in rooting hormone, and plant them in moist, well-drained soil mix or sandy soil. Keep the cuttings in a shaded or partially shaded area and keep them moist until they establish roots.
Division
Draba reptans ssp. stellifera can also be propagated through division. Divide the plant during its dormant season in the fall or early spring. Carefully dig up the plant, separate the root ball into two or more sections, and replant each section in a suitable location. Ensure that each section has enough roots and shoots to establish successfully.
Disease Management
Draba reptans ssp. stellifera is susceptible to various fungal and bacterial diseases, including:
- Anthracnose
- Downy mildew
- Root rot
- Crown rot
- Bacterial leaf spot
To manage these diseases, it is essential to maintain good sanitation practices. Remove and dispose of infected plant debris and avoid overhead watering. Apply a fungicide or bactericide to the plant, following the manufacturer's instructions.
Pest Management
Draba reptans ssp. stellifera is susceptible to infestations from various pests, including:
- Aphids
- Cabbage loopers
- Cutworms
- Wireworms
- Spider mites
To manage these pests, consider using natural controls such as introducing natural predators like lady beetles or spraying the plant with insecticidal soap. You can also use chemical insecticides; however, you should read and adhere to manufacturer instructions. Additionally, avoid overwatering, which can increase the likelihood of pest infestation.
