Overview
Calycadenia multiglandulosa DC. is a flowering plant native to California, United States. It is a part of the Asteraceae family and is commonly known by its various names including sticky calycadenia, stickyhead, and stickywhite. The plant is known for its unique appearance and medicinal properties.
Appearance
Calycadenia multiglandulosa DC. is a small perennial plant that can grow up to 16 inches in height. It has a woody base and small green leaves that are covered with fine white hairs. The plant produces small, yellow flowers that grow in clusters at the top of the stem. The most distinctive feature of the plant is its sticky, resinous glandular hairs that cover the stems and leaves. These glands produce a strong, fragrant aroma when crushed or bruised.
Uses
The sticky calycadenia has been used traditionally by Native Americans to treat various ailments including fever, stomach pains, and respiratory problems. The glands on the plant contain a resinous substance that has antiseptic and anti-inflammatory properties. The plant is also cultivated for its ornamental value as it adds a unique texture and fragrance to gardens and landscapes.
Furthermore, sticky calycadenia is used in the perfume industry to create aromatic oils. The essential oil from this plant has a strong, resinous aroma that is reminiscent of pine and cedarwood. Calycadenia multiglandulosa DC. is a useful plant with various benefits, both medicinal and ornamental.
Light Conditions
Calycadenia multiglandulosa DC. commonly grows in areas with full sun exposure, although some shade is also tolerable. It is recommended to provide at least 6 hours of direct sunlight per day for optimal growth.
Temperature Requirements
Calycadenia multiglandulosa DC. thrives in warm temperature conditions. The ideal temperature range for growth is between 60-80°F (15-27°C). It is essential to maintain stable temperatures and avoid extreme fluctuations to prevent any damage or stress to the plant.
Soil Requirements
Calycadenia multiglandulosa DC. requires well-draining soil with a pH range between 6-8. The plant can tolerate different types of soil, but it prefers sandy or loamy soil with moderate fertility. Adequate soil moisture is necessary, but overwatering should be avoided at all costs, as it can lead to root rot.
Cultivation Methods:
Calycadenia multiglandulosa DC. is a low-maintenance plant that thrives in well-draining soil. It grows best in full sun and can tolerate a range of temperatures but prefers a warm, dry climate. It is an excellent choice for rock gardens and containers. The plant prefers alkaline soils and may require lime application to decrease acidity. It is important to remove weeds and debris to prevent disease and maintain soil moisture.
Watering Needs:
Calycadenia multiglandulosa DC. requires moderate watering, mainly during the growing season. Ensure that the topsoil is moist before watering and avoid overwatering, as it can lead to root rot. Water the plant thoroughly less frequently, rather than a light sprinkling more frequently, as it promotes healthy root growth and prevents fungal growth. Mulching around the plant can also help retain soil moisture and suppress weeds.
Fertilization:
The plant does not require heavy fertilization as excess nutrients can lead to excessive vegetative growth and decreased flowering. Apply a balanced fertilizer (10-10-10) every two to three weeks during the growing season. Alternatively, a slow-release fertilizer can be applied once during the growing season to provide the necessary nutrients.
Pruning:
Calycadenia multiglandulosa DC. does not require regular pruning. If the plant appears leggy or overgrown, it can be pruned back to promote bushier growth. Remove any dead or diseased growth to maintain the plant's health. Pinching back the tips of the stems can also encourage branching and fuller growth. It is best to prune the plant after flowering to avoid disrupting the flowering cycle.
Propagation of Calycadenia multiglandulosa DC.
Calycadenia multiglandulosa DC., commonly known as the stickyhead, is a perennial herbaceous plant native to California, United States. It is commonly propagated by seeds and cuttings.
Propagation by Seeds
The seeds of Calycadenia multiglandulosa are small and smooth, measuring about 1-2 mm in size. They can be collected from the plant when they turn brown and are fully mature. The seeds are sown in well-draining potting soil or garden soil that has been loosened up to a depth of 15 cm. It is advisable to sow the seeds in early spring, as this will allow the seedlings to establish themselves before the hot summer months. The seeds should be sown at a depth of 1-2 cm, and the soil should be kept moist but not waterlogged. Germination usually takes 2-3 weeks, after which the seedlings can be transplanted to their permanent location.
Propagation by Cuttings
Calycadenia multiglandulosa can also be propagated by stem cuttings taken in late spring or early summer. Select healthy stems that are about 15-20 cm in length and snip them off at the base with a clean pair of pruning shears. Remove the lower leaves, leaving only a few at the tip. Dip the cut end of the stem in rooting hormone and insert it into a container with damp potting soil. Cover the container with a clear plastic bag, making sure the leaves don't touch the plastic. Place the container in a bright, indirect light location and keep the soil moist. Roots should form within 4-6 weeks, at which point you can transplant the cutting to its permanent location.
Disease and Pest Management for Calycadenia multiglandulosa
Calycadenia multiglandulosa is a hardy plant that can be affected by common diseases and pests. Here are some tips on how to manage these issues:
Common Diseases
Root Rot: This disease is caused by overwatering or poor drainage. To prevent and manage root rot, make sure the soil is well-draining and do not water excessively. You may need to replant infected plants in fresh soil if the condition is severe.
Powdery Mildew: This fungal disease first appears as a white powdery substance on the leaves. To manage powdery mildew, remove infected leaves immediately and apply a copper fungicide to prevent the disease from spreading to other parts of the plant.
Leaf Spot: This disease is caused by a fungal or bacterial infection and appears as brown or black spots on the leaves. To manage leaf spot, remove infected leaves and apply a copper-based fungicide. Make sure you provide enough air circulation to the plant by spacing them properly.
Common Pests
Aphids: Aphids are small insects that feed on the leaves and stems of the plant. They can cause significant damage if left unchecked. To manage aphids, spray the plant with a strong stream of water or apply insecticidal soaps or oils. You may need to repeat the treatment every few days until the pests are gone.
Spider Mites: Spider mites are tiny pests that cause discoloration and distortion of the leaves. To manage spider mites, use a strong stream of water to knock them off the leaves. You can also apply insecticidal soaps or oils to control the population.
Thrips: Thrips are tiny insects that feed on the flowers and buds of the plant, causing damage or distortion. To manage thrips, use sticky traps or apply insecticidal soaps or oils. Neem oil can also be used as a natural alternative to chemical pesticides.
Be sure to regularly inspect your Calycadenia multiglandulosa for diseases and pests and take action as soon as you notice any issues. Healthy plants are less likely to attract pests and diseases, so make sure you provide optimal growing conditions.
