Overview
Beckwithia andersonii (Gray) Jepson, commonly known as Anderson's desert parsley or Anderson's beckwithia, is a biennial or perennial herbaceous plant belonging to the Apiaceae family. This plant is native to the western United States and is found in various habitats, including limestone outcrops, rocky slopes, and desert washes.
Appearance
Beckwithia andersonii grows up to 2-3 feet tall and has compact, bushy, and highly branched stems. The leaves are basal and have long petioles, while the stem leaves are alternate, compound, and pinnate, with linear-lanceolate, sharply toothed leaflets. The flowers of this plant are small, white to pale pink, and arranged in a terminal umbel, which blooms from May to August.
Uses
Beckwithia andersonii is used as a medicinal plant by Native Americans. They use a decoction of the roots and stems to treat diarrhea, fever, headaches, and menstrual disorders. The crushed leaves and fruits are applied topically to relieve joint, muscle, and rheumatic pains. This plant is also an important source of food for wildlife, especially for the sage grouse, which feeds on its seeds and leaves.
Growth Conditions of Beckwithia andersonii
Beckwithia andersonii, commonly known as Anderson's rockcress, is a perennial herbaceous plant found in mountainous regions of western North America. The plant is well-adapted to growing in rocky, gravelly soils which receive limited rainfall. Below are the growth conditions required for optimal growth of Beckwithia andersonii:
Light
This plant thrives in an environment with full sun to partial shade. A sunny location is preferable, but the plant can tolerate some shade. Inadequate light can result in stretched, spindly plants with reduced flower production.
Soil Requirements
Anderson's rockcress prefers well-drained soils with a coarse texture and low fertility. The plant can tolerate slightly acidic to alkaline soils. A rocky or gravelly substrate is ideal, and plants are often found growing in rock crevices or other harsh environments. The plant will not tolerate heavy clay soils or soil with poor drainage.
Temperature
Beckwithia andersonii prefers cool to cold climatic conditions. It is well-adapted to high elevations and can tolerate freezing temperatures. However, it will not grow in extremely hot or humid environments.
Water
This plant requires very little water and can survive extended periods of drought. In fact, over-watering can be detrimental to the plant's growth and survival. It is important to allow the soil to dry out completely between watering.
Cultivation Methods
Beckwithia andersonii is a relatively low-maintenance plant that is quite easy to cultivate. The plant prefers to grow in well-drained soil with a slightly acidic pH. It tolerates partial shade but grows best in full sun. It is best to plant Beckwithia andersonii in the spring or fall. The plant is an excellent option for rock gardens, borders, and groundcovers.
Watering Needs
Beckwithia andersonii requires frequent watering, especially during the first year of growth, to help establish a healthy root system. The plant should be watered once a week during the growing season, depending on rainfall and temperature. During periods of extended drought, the plant may need additional watering. Avoid overwatering, as this can lead to rot and fungal growth.
Fertilization
The plant does not require a lot of fertilization. Beckwithia andersonii benefits from a light application of a balanced fertilizer in the spring. Over-fertilizing can negatively affect the plant's growth and overall health. It is essential to follow the instructions on the fertilizer packaging and not exceed the recommended rates.
Pruning
Beckwithia andersonii does not require regular pruning. However, it is advisable to remove any dead stems and leaves as they appear. This helps to maintain the plant's shape, appearance, and overall vitality. Pruning should be done in late winter or early spring before the new growth appears.
Propagation of Beckwithia andersonii
Beckwithia andersonii (Gray) Jepson is a rare and endemic wildflower species in California. As it is considered rare, propagation methods have not been extensively studied. However, there are a few known ways to propagate this plant.
Seed Propagation
Since Beckwithia andersonii produces seed heads, it is possible to propagate the plant through seeds. The seeds mature in the months of July and August, and you can collect them by hand from the plant when the flower heads turn brown. Sow the seeds outside in the fall, and the seeds will need to be watered well until germination. It is important to note that the seeds may take several years to germinate, so be patient.
Division Propagation
If the plant is mature enough, you can try to propagate it through dividing the plant's rhizomes. Dividing the rhizomes is most effective in the spring after the bloom. You can divide the plants into sections and replant them in new locations. Making sure that the newly separated section has roots with it is very important for the success of this method.
Cuttings Propagation
Cuttings are another way to propagate Beckwithia andersonii. Take stem cuttings of 4-6 inches(10-15cm) and place them in potting soil. Ensure that the pots are kept moist, and they will soon root. You can use rooting hormones to aid in rooting if you choose. The best time to take cuttings is late spring or early summer, but it is possible to take cuttings through the growing season.
These are a few of the propagation methods known for Beckwithia andersonii. It is important to note that the plant is rare and scarce, and over propagation of the species is discouraged. Therefore, carefully consider the methods and plants before propagating.
Disease and Pest Management for Beckwithia andersonii
Beckwithia andersonii is a hardy plant that is resistant to most pests and diseases, making it a popular choice for gardens and landscapes. However, it can still be affected by a few common plant diseases and pests, which can decrease its growth and appearance. To keep Beckwithia andersonii healthy and vigorous, it is important to implement proper disease and pest management techniques.
Common Diseases
One common disease that affects Beckwithia andersonii is powdery mildew, which appears as a powdery white coating on the leaves and stems. This disease is caused by fungal spores and is usually a result of high humidity and poor air circulation. To prevent powdery mildew, make sure the soil is well-draining and avoid overwatering the plant. If the disease does appear, prune away any infected parts and treat the plant with a fungicide.
Another disease that can affect Beckwithia andersonii is leaf spot, which appears as dark spots on the leaves and can lead to defoliation. This disease is caused by a fungal infection and is spread by water. To prevent leaf spot, avoid overhead watering and plant the Beckwithia andersonii in a location with good air circulation. If the disease does appear, remove any infected leaves and treat the plant with a fungicide.
Common Pests
Beckwithia andersonii is generally resistant to most pests, but it can still be affected by spider mites. These pests are small and can be difficult to see with the naked eye, but they can cause damage by sucking the sap from the leaves and causing yellowing and curling of the foliage. To prevent spider mites, make sure the plant is well-watered and mist the foliage regularly. If spider mites do appear, treat the plant with an insecticidal soap or neem oil.
Another pest that can affect Beckwithia andersonii is aphids, which are small, soft-bodied insects that can be found on the leaves and stems. They can cause damage by sucking the sap from the plant and leaving behind a sticky residue. To prevent aphids, keep the plant well-watered and remove any nearby weeds or other plants that may attract them. If aphids do appear, treat the plant with an insecticidal soap or neem oil.
Conclusion
By implementing proper disease and pest management techniques, you can ensure that your Beckwithia andersonii remains healthy and vibrant. Make sure to keep the plant well-watered, avoid overhead watering, and maintain good air circulation. If disease or pests do appear, take immediate action to prevent them from spreading and treat the plant with appropriate fungicides or insecticides.
