Overview:
Cleomella plocasperma S. Wats. is a perennial plant species that belongs to the Cleomaceae family. This plant is native to the southwestern part of North America, specifically found in the states of California, Nevada, and Colorado. It is commonly known as spiny cleomella, and its scientific name, ‘plocasperma’ means ‘crowded seeds’ that refers to the densely packed seeds of the plant.
General Appearance:
The spiny Cleomella plocasperma plant is characterized by its stout and branched stems that grow up to 10cm to 30cm tall. This plant has alternate leaves that are composed of 3 leaflets, each measuring up to 2.5cm long and 1cm wide. Its leaves are bright green and have toothed margins. The plant produces small, white-colored flowers that are clustered on a slender raceme that is flat-topped.
Uses:
Spiny Cleomella plocasperma has been traditionally used by Native Americans to treat a range of ailments, including sore throats, colds, and stomach problems. It is also used as a tea and has a mild taste and is slightly sweet.
The spiny Cleomella plocasperma has also been used widely in the cosmetic industry in the preparation of soaps, oils, and lotions because of its antioxidant properties. It contains various bioactive compounds such as flavonoids that have potent antioxidant properties that protect the skin from damage caused by free radicals.
In addition, this plant is known for its ornamental value as it can be grown as an ornamental plant in gardens and landscapes, especially in arid climates.
Light Requirements
Cleomella plocasperma S. Wats. is a plant that requires plenty of sunlight to grow properly. It is best suited for areas that receive full sun exposure for most of the day. In areas with insufficient sunlight, the plant will struggle to photosynthesize and may not produce adequate blooms.
Temperature Requirements
The Cleomella plocasperma S. Wats. plant is adapted to dry climates and prefers warm temperatures ranging between 70°F to 85°F (21°C to 29°C). It can tolerate some exposure to cooler temperatures but will not survive in frosty conditions. If grown in environments with fluctuating temperatures, it is essential that daytime temperatures remain higher and there is a significant drop in temperature at night.
Soil Requirements
Cleomella plocasperma S. Wats. grows well in well-drained soils that are moist but not soggy. The plant's roots are susceptible to rot if they become waterlogged. The pH level required by Cleomella plocasperma S. Wats. is slightly acidic to neutral, with a range of 5.0 to 7.5. Enriched soils are best suited for this plant, where they provide a steady and consistent amount of nutrients throughout the growing season.
Cultivation methods for Cleomella plocasperma S. Wats.
Cleomella plocasperma S. Wats. is a hardy desert plant that grows well in USDA hardiness zones 8 to 11. It prefers full sun and well-draining soil that is slightly alkaline. The plant can be propagated from seed or cuttings.
For best results, sow the seeds in the late fall or winter. The seedlings can be transplanted outdoors when they are large enough to handle and the threat of frost has passed. Cuttings can be taken in the spring or summer, and should be placed in a moist rooting medium until they develop roots.
Watering needs for Cleomella plocasperma S. Wats.
Cleomella plocasperma S. Wats. is a drought-tolerant plant that requires infrequent watering. Water deeply and infrequently, allowing the soil to dry out between waterings. In hot, dry climates, the plant may require slightly more frequent irrigation. Overwatering can lead to root rot and other diseases.
Fertilization of Cleomella plocasperma S. Wats.
Cleomella plocasperma S. Wats. does not require much fertilization. Applying a slow-release, low-nitrogen fertilizer in the spring can help promote healthy growth. Avoid over-fertilizing, as this can cause the plant to become leggy and weak.
Pruning of Cleomella plocasperma S. Wats.
Pruning is usually not necessary for Cleomella plocasperma S. Wats. However, if the plant becomes too leggy or crowded, it can be lightly pruned in the late winter or early spring. Remove any dead or damaged growth, and cut back any excessively long branches. Avoid heavy pruning, as this can damage the plant and reduce flowering.
Propagation of Cleomella plocasperma S. Wats.
Cleomella plocasperma S. Wats., commonly known as spiderflower, is a herbaceous plant that belongs to the Cleomaceae family. It is native to southwestern United States and northern Mexico, where it grows in dry sandy soils, rocky slopes, and desert washes. It is a popular garden plant due to its attractive purple flowers that bloom in early to mid-summer. Here are the different methods of propagating Cleomella plocasperma:
Seeds
The most common method of propagating Cleomella plocasperma is by seed. The plant produces small, black seeds that can be easily collected once the seed pods have dried. To collect seeds, wait until the pods turn brown and start to split open. Harvest the pods, and spread them out to dry completely. Once dried, gently tap them to release the seeds.
Sow the seeds in well-draining soil, either indoors or outdoors, in early spring after the last frost. Cover the seeds with a thin layer of soil, and keep them moist until they germinate. The seeds usually germinate within 7 to 21 days.
Cuttings
Cleomella plocasperma can also be propagated by stem cuttings. Take a stem cutting from a healthy, mature plant in the spring or summer and remove the bottom leaves. Dip the cut end in rooting hormone to increase the chances of success. Plant the cutting in a small container filled with well-draining soil and cover it with a plastic bag to create a humid environment. Place the container in a warm, bright location, and keep the soil moist until the cutting develops roots.
Division
The herbaceous nature of Cleomella plocasperma makes it a good candidate for division. Dig up the plant in the spring or fall, and use a clean, sharp knife to cut the plant into sections. Each section should have at least one growing shoot and a good root system. Replant the sections in well-prepared soil, and water them thoroughly.
Propagation of Cleomella plocasperma is relatively easy and can be achieved through seeds, stem cuttings, and division. With the right care and conditions, the plant will reward you with its beautiful blooms.
Disease and Pest Management for Cleomella plocasperma S. Wats.
Cleomella plocasperma S. Wats., commonly known as threadstem cleomella, is a hardy perennial plant that thrives in arid and semi-arid regions. Although it is relatively resistant to diseases and pests, there are several common issues that gardeners may encounter while cultivating this plant.
Common Diseases
One common disease that affects Cleomella plocasperma is powdery mildew. This fungal infection appears as a white or gray powder on the leaves and stems and can stunt the growth of the plant. To prevent powdery mildew, avoid overwatering and provide good air circulation around the plant. If powdery mildew appears, prune infected parts immediately and apply a fungicide according to the manufacturer's instructions.
Anthrax is another fungal disease that can affect Cleomella plocasperma. It causes the leaves to yellow and wilt and can ultimately lead to the death of the plant. To prevent anthrax, ensure that the soil is well-draining and avoid overcrowding the plants. If anthrax appears, remove infected parts and dispose of them properly. You can also apply a fungicide to the remaining parts of the plant.
Common Pests
Cleomella plocasperma is relatively resistant to pests, but there are a few insects that gardeners need to watch out for. One of the most common pests is the aphid. These tiny insects suck sap from the plant, leaving it weak and susceptible to disease. To control aphids, spray the plant with a strong jet of water to dislodge them or apply an insecticidal soap according to the manufacturer's instructions.
Another common pest that can affect Cleomella plocasperma is the spider mite. These tiny pests are difficult to see with the naked eye but can cause significant damage to the plant by sucking sap and leaving behind a fine webbing. To control spider mites, spray the plant with a strong jet of water or apply a miticide according to the manufacturer's instructions.
In summary, Cleomella plocasperma is a hardy plant that resists diseases and pests relatively well. However, gardeners need to watch out for powdery mildew, anthrax, aphids, and spider mites. By following good cultural practices and taking prompt action when issues arise, gardeners can keep Cleomella plocasperma healthy and productive.
