Cleome serrata Jacq. belongs to the Cleomaceae family and is commonly known as Rocky Mountain beeplant. It is a herbaceous, annual plant that can reach up to a height of 3-4 feet.
Light
Cleome serrata Jacq. thrives in full sun to partial shade conditions. It requires at least 6-8 hours of direct sunlight per day to grow and flower optimally.
Temperature
Cleome serrata Jacq. prefers moderate temperatures and cannot tolerate extreme cold or heat conditions. The ideal temperature range for its growth is between 60-75°F (15-24°C). It can also survive in slightly lower temperatures, but frost can damage the plant severely.
Soil
Cleome serrata Jacq. prefers well-draining soil with a pH range between 6.0-7.5. It can grow in various soil types, including sandy, loamy, or clay soils. The plant does not tolerate waterlogged or poorly drained soils and may suffer from root rot. A soil rich in organic matter is recommended to promote healthy growth.
Water
Cleome serrata Jacq. requires moderate watering, and the soil should be kept moist but not waterlogged. Overwatering can lead to root rot, while underwatering can cause the plant to wilt and stress. It is recommended to water the plant deeply once a week, or when the top inch of soil feels dry to the touch.
Fertilizer
Cleome serrata Jacq. is not a heavy feeder and can grow well without fertilization. However, applying a balanced fertilizer once every two weeks during the growing season can promote healthy growth and flowering. Avoid applying excessive nitrogen fertilizer, as this can lead to lush, leafy growth and reduced flowering.
By providing suitable growth conditions, Cleome serrata Jacq. can thrive and produce vibrant flowers that attract bees, butterflies, and hummingbirds.
Cultivation methods
Cleome serrata Jacq., commonly referred to as Rocky Mountain bee plant, is a hardy annual plant that thrives in full sun and rich, well-draining soil. It can grow up to 4 feet tall and 1-2 feet wide, making it an excellent choice for a plant border or a standalone specimen. The plant can be grown from seed and prefers cooler temperatures. It is hardy in USDA zones 3-10.
Watering needs
While Cleome serrata Jacq. prefers well-draining soil, it still needs consistent water to thrive. Water deeply once or twice a week, depending on rainfall and humidity. Ensure that the soil is well-draining, as standing water can cause root rot. During periods of drought, increase watering to keep the soil moist. Avoid overhead watering, as it can promote the spread of disease.
Fertilization
Cleome serrata Jacq. benefits from a balanced fertilizer application in the early spring, before new growth begins. Use an all-purpose fertilizer, such as a 10-10-10, and apply according to the manufacturer's instructions. Too much fertilizer can result in overly bushy growth and fewer flowers, so be sure not to overapply.
Pruning
Cleome serrata Jacq. benefits from light pruning throughout the growing season. Pinch off spent blooms to promote continuous flowering, and snip back any leggy growth to promote bushier growth. In the fall, cut back the entire plant to the ground to prepare for winter dormancy. This will also help prevent self-seeding, as Cleome serrata Jacq. can be an aggressive self-seeder.
Propagation of Cleome Serrata Jacq.
Cleome serrata Jacq. can be propagated through several methods which include:
Seeds
Propagation via seeds is the most common method for Cleome serrata Jacq. Seeds of this plant can be sown directly into the soil during early spring after the last frost. The seeds must be sown at a depth of 1 cm and spaced about 30 cm apart. The germination process typically takes around 3 to 4 weeks, and once the seedlings reach a height of 5 to 10 cm, they can be carefully transplanted to their permanent position. This method of propagation is easy and has a high success rate.
Cuttings
Cleome serrata Jacq. can also be propagated through cuttings. For this method of propagation, choose healthy stem cuttings from a mature plant. Cut the stem at an angle of 45 degrees and remove the bottom leaves. Dip the cut end in rooting hormone powder and plant it in a pot filled with moist soil. Put the pot in a warm and shaded area to promote rooting. Once rooted, the cuttings are ready for transplantation to their permanent position.
Division
Cleome serrata Jacq. can be propagated through division. This method involves separating the root clumps into smaller sections and then planting them in a well-prepared bed. Ensure that each section has a few stems and leaves attached to promote growth. Water the newly planted sections regularly until they establish.
Tissue Culture
Propagation via tissue culture is a more advanced method and typically done in research facilities. Tissue culture involves growing the plant from its cells in a sterile laboratory condition. This method is more expensive and requires technical knowledge, but it has a high success rate.
Disease and Pest Management for Cleome serrata Jacq.
Cleome serrata Jacq., also known as Rocky Mountain beeplant or stinking clover, is a crucial component in pollinator gardens. However, the plant is susceptible to various diseases and pests, which can cause significant damage if not properly managed.
Common Diseases
One of the most common diseases that affect Cleome serrata Jacq. is powdery mildew. Powdery mildew is a fungal disease that thrives in warm and humid conditions. The disease causes a white powdery substance to appear on the surface of the plant's leaves, which can ultimately lead to leaf drop and plant death. To manage powdery mildew, gardeners should ensure that the plant has adequate air circulation and avoid overhead watering. Additionally, gardeners can apply a fungicide to manage the disease.
Another common disease that affects Cleome serrata Jacq. is leaf spot. Leaf spot is caused by the fungal pathogen Mycosphaerella violae. The disease causes yellow to brown lesions on the leaves, which can cause the leaves to drop prematurely. To manage leaf spot, gardeners should avoid overhead watering and ensure that the plant has proper air circulation. Additionally, gardeners can apply a fungicide to manage the disease.
Common Pests
Cleome serrata Jacq. is also susceptible to various pests, including aphids, spider mites, and whiteflies. These pests feed on the plant's sap, which can cause the leaves to yellow and curl, stunt plant growth, and transmit diseases. To manage these pests, gardeners can spray the plant with a strong jet of water to knock off the insects. Additionally, introducing natural predators, such as ladybugs or lacewings, can help control the pest population. If these methods are not effective, gardeners can use an insecticidal soap to manage the pests.
Another common pest that affects Cleome serrata Jacq. is the flea beetle. Flea beetles feed on the plant's leaves, which can cause small holes in the foliage. The pests can cause significant damage if left unchecked. To manage flea beetles, gardeners can apply a neem oil or pyrethrin-based insecticide. Alternatively, gardeners can cover the plant with a floating row cover to prevent the beetles from reaching the plant.
By managing diseases and pests effectively, gardeners can ensure that Cleome serrata Jacq. remains healthy and productive in their gardens.
