The plant can grow up to 1–2 feet in height and has finely hairy leaves that are about 1-3 inches long and 0.1-0.7 inch wide. The leaves have distinctive aromas, and the tips of the leaves have small glands that produce a fragrant oil. The plant produces bright yellow flowers that bloom in mid-August through late October with numerous heads in elongated clusters.
Uses of Heterotheca camporum (Greene) Shinners var. glandulissimum Semple
The Texas Yellow Star is often grown for ornamental purposes in gardens, parks, and naturalized plantings. The plant is also used as a food source for butterflies, bees, and other pollinators. Medicinally, it has been utilized by Native Americans to soothe pain, headaches, and fever.
Overall, the Heterotheca camporum (Greene) Shinners var. glandulissimum Semple is an attractive and aromatic plant that is easily grown and maintained. Its distinctive features make it a unique addition to any garden or pollinator habitat.
Light requirements:
Heterotheca camporum var. glandulissimum prefers to grow in full sun, but can tolerate partial shade.
Temperature requirements:
This plant can survive in a wide range of temperatures, from hot summers to cold winters. It is native to areas with hot summers that can reach up to 38°C (100°F), and cold winters that can drop to -12°C (10°F).
Soil requirements:
Heterotheca camporum var. glandulissimum prefers well-draining soils with a pH range of 5.5 to 7.5. It can tolerate poor soils, but it does better in soils with higher organic matter content.
Additionally, the soil should be moist but not waterlogged. This plant can tolerate short periods of drought, but it does not do well in consistently dry conditions.
Cultivation methods
Heterotheca camporum (Greene) Shinners var. glandulissimum Semple, also known as the Texas goldenaster, is a hardy and rugged perennial plant native to North America. It thrives best in well-drained soils with a pH range of 6 to 8.
Propagation can be done via seeds or vegetative division. Seeds should be sown in early spring or late fall in a well-prepared soil bed and covered with a thin layer of soil. For vegetative propagation, divide the plant in early spring before the new growth emerges.
Watering needs
The Texas goldenaster is a drought-tolerant plant, and overwatering can cause root rot. Water only when the soil is dry to the touch, and make sure the water penetrates to the roots. Deep but infrequent watering is recommended.
Fertilization
The Texas goldenaster is not a heavy feeder, and too much fertilizer can lead to excessive growth with fewer flowers. Fertilization should be done in early spring with a balanced fertilizer. Use a slow-release granular fertilizer and apply it according to the manufacturer's instructions. Alternatively, use a liquid fertilizer diluted with water and apply it every two weeks during the growing season.
Pruning
Pruning of the Texas goldenaster can help to prevent the plant from becoming too leggy and woody. Prune in the late fall or early spring before new growth emerges. Cut back the stems to about one-third of their height. Deadhead regularly by removing spent flowers to encourage more blooms.
Propagation of Heterotheca camporum var. glandulissimum Semple
Heterotheca camporum var. glandulissimum Semple is commonly known as the Texas golden aster. This plant can be propagated through various methods such as seed propagation, stem cuttings, and division.
Seed Propagation
The easiest and most common method of propagating Heterotheca camporum var. glandulissimum is through seeds. The seeds of this plant can be collected once they are matured in the fall. The collected seeds can be sowed directly in the ground after the last frost, or they can be stored until the following spring. The seeds should be sowed in an area with well-drained soil and full sunlight. They do not require any pre-treatment to germinate. Once the seeds have been sowed, they should be watered regularly to ensure they remain moist until they germinate.
Stem Cuttings
Heterotheca camporum var. glandulissimum can also be propagated through stem cuttings. Take 3-4 inch cuttings from the stem tips of the plant in the spring or summer. Remove the leaves from the bottom of the stem, leaving only a few at the tip. Dip the cuttings in rooting hormone, gently tap off any excess powder, and plant in a well-draining soil mixture. Keep the soil moist and place the cutting in a bright, indirect light location. The cuttings should root within a few weeks.
Division
Heterotheca camporum var. glandulissimum can also be propagated through division. Once the plant has established itself, dig around the root-ball and carefully separate the plant into multiple sections. Each section should have its own roots and shoots. Transplant the divisions into individual containers or directly into the garden. Water the newly transplanted divisions regularly until they are established.
Disease Management
Heterotheca camporum is generally a healthy plant that is not susceptible to many diseases. However, some common diseases that may affect this plant include:
- Leaf Spot: Leaf spot is caused by fungal pathogens and is characterized by the presence of dark spots on the leaves. To manage leaf spot, remove the affected leaves and dispose of them. Avoid overhead watering and improve air circulation around the plant.
- Powdery Mildew: Powdery mildew is caused by a fungal pathogen and is characterized by a white powdery coating on the leaves of the plant. To manage powdery mildew, treat the plant with a fungicide and improve air circulation around the plant.
- Root Rot: Root rot is caused by fungal pathogens that attack the roots of the plant. To manage root rot, avoid overwatering and ensure that the soil is well-drained. Treat the plant with a fungicide if necessary.
Pest Management
Some common pests that may affect Heterotheca camporum include:
- Aphids: Aphids are small, soft-bodied insects that feed on the sap of the plant. To manage aphids, wash the plant with a strong stream of water or treat with insecticidal soap or neem oil.
- Spider Mites: Spider mites are tiny pests that suck sap from the leaves of the plant and cause a speckled appearance. To manage spider mites, wash the plant with a strong stream of water or treat with insecticidal soap or neem oil.
- Thrips: Thrips are tiny, slender insects that feed on the leaves of the plant. To manage thrips, remove and dispose of affected leaves. Treat the plant with an insecticide if necessary.
Regular monitoring and proper cultural practices such as proper watering, fertilization, and pruning can help prevent pest and disease problems. In addition, practicing crop rotation and using disease-resistant varieties of plants can also help prevent disease problems.
