Its yellow flowers bloom from May to August and have diameter ranging from 2-4 cm.Uses
This plant is not commonly used for medicinal purposes, but the Native Americans have used it to treat various ailments such as diarrhea, stomach aches, and rheumatism. Its leaves and flowers can also be used to make a flavorful tea.Conservation
The Calycadenia multiglandulosa DC. ssp. robusta Keck is listed as a species of least concern by the International Union for Conservation of Nature (IUCN). Although some populations have been impacted by climate change and urbanization, this species has a relatively large distribution and is not currently under significant threats.Growth Conditions for Calycadenia multiglandulosa DC. ssp. robusta Keck
Calycadenia multiglandulosa DC. ssp. robusta Keck, also known as the sticky bird’s beak, is a small annual plant that belongs to the sunflower family (Asteraceae). It is native to California and is often found growing in coastal sage scrub and chaparral habitats.
Light Requirements
The sticky bird’s beak requires full sun to grow, which means it needs at least six hours of direct sunlight per day. Without proper sunlight, the plant may not grow and flower properly.
Temperature Requirements
The sticky bird’s beak thrives in warm weather and is generally found in habitats that have mild temperatures. It grows best in temperatures ranging from 60°F to 80°F. Extreme heat can cause the plant to wilt, so it is important to provide some shade during hot summer days.
Soil Requirements
The sticky bird’s beak requires well-draining soil that is sandy or loamy. It can tolerate a wide range of soil pH levels, but prefers slightly acidic to neutral soil (pH 6.0 to 7.5). The plant may not grow properly in soil that is heavy and clay-like. It is important not to over-water the plant as it may cause root rot.
Overall, the sticky bird’s beak is a hardy plant that can tolerate a range of growing conditions, but it requires adequate sunlight, warm temperatures, and well-draining soil to grow properly.
Cultivation
Calycadenia multiglandulosa DC. ssp. robusta Keck is native to the coastal areas of California and prefers to grow in well-draining soil with full sun exposure. It is a drought-tolerant plant and requires very little water, making it an excellent choice for water-wise gardens. When planting, make sure to space the plants 12-18 inches apart.
Watering Needs
As mentioned earlier, Calycadenia multiglandulosa DC. ssp. robusta Keck is a drought-tolerant plant and requires little water. During the growing season, it needs watering only once every two weeks. Water the plant deeply, but make sure to allow the soil to dry out before watering again. Overwatering can lead to root rot, so make sure not to water the plant too often.
Fertilization
Calycadenia multiglandulosa DC. ssp. robusta Keck does not require much fertilization, but you can fertilize once or twice a year during the growing season to encourage blooming. Use a balanced fertilizer with equal amounts of nitrogen, phosphorus, and potassium. Follow the instructions on the package for the correct dosage and apply the fertilizer around the base of the plant, taking care not to get any on the leaves or stems.
Pruning
Pruning is not necessary for Calycadenia multiglandulosa DC. ssp. robusta Keck, but you can deadhead the spent blooms to encourage new growth and prolong the blooming season. Cut off the spent blooms just below the flower head using a pair of clean and sharp pruning shears. If the plant is growing out of shape or size, you can prune it back in the early spring to promote bushier growth.
Propagation of Calycadenia multiglandulosa DC. ssp. robusta Keck
Calycadenia multiglandulosa DC. ssp. robusta Keck has several methods of propagation, including the use of seeds and stem cuttings. The propagation method used may depend on the gardener's preference and the current status of the plant.
Propagation by Seeds
Seeds from Calycadenia multiglandulosa DC. ssp. robusta Keck can be collected from the previous flowering season. The best time to collect the seeds is when the flowers have completely dried out, and the seeds have turned brown. The collected seeds can be kept in a dry, cool place until the next planting season, which is typically in the spring.
For sowing, the seeds should be pre-treated with a cold, moist stratification process to increase their germination rate. The seeds can be sown in seed trays, and once they have sprouted, they can be transferred to individual pots. The seedlings should be kept in a sheltered, warm spot until they are ready to be planted in the garden.
Propagation by Stem Cuttings
Propagation by stem cuttings is another method used for Calycadenia multiglandulosa DC. ssp. robusta Keck. This method is typically done in the late spring or early summer when the plant is in its active growing phase. The cuttings should be taken from the plant's new growth, and they should be approximately four inches long.
The cuttings should be dipped in a rooting hormone and planted in a well-draining potting mix. The pot should be kept moist but not waterlogged, and the cuttings should be kept in a warm, sheltered location until they have taken root. Once rooted, the new plants can be transplanted into the garden or into individual pots.
Disease Management
Calycadenia multiglandulosa DC. ssp. robusta Keck is susceptible to various types of diseases which can affect the growth and productivity of the plant. Some of the common diseases that may affect the plant include:
- Root rot: This is a fungal disease that can cause decay of the roots of the plant, leading to poor growth and wilting of the leaves. To manage this disease, it is important to avoid overwatering and to ensure proper drainage. Infected plants should be removed and destroyed.
- Powdery mildew: This fungal disease appears as a white powdery coating on the leaves of the plant. It can reduce photosynthesis and affect the plant's growth. To manage powdery mildew, remove infected leaves and ensure proper ventilation and sunlight penetration. Fungicides may also be used.
- Leaf spot: This is a fungal disease that appears as small black spots on the leaves of the plant. To manage leaf spot, remove infected leaves and ensure proper sanitation. Fungicides can also be used.
Pest Management
Calycadenia multiglandulosa DC. ssp. robusta Keck can also be affected by various pests, which can cause significant damage to the plant. Some of the common pests that may affect the plant include:
- Aphids: These are small insects that suck the sap from the plant, causing stunted growth and yellowing of the leaves. To manage aphids, use insecticidal soap or neem oil, or introduce natural predators such as ladybugs and lacewings.
- Spider mites: These are small insects that can cause discoloration and wilting of the leaves. To manage spider mites, clean the plant with water, use insecticidal soap or neem oil, or introduce natural predators such as ladybugs and predatory mites.
- Caterpillars: These are larvae of moths and butterflies that can eat the leaves of the plant, causing significant damage. To manage caterpillars, handpick them off the plant or use insecticides.
