It has thistle-like leaves that are spiny and flowers that are bright yellow in color. The flowers are arranged in a cluster at the top of the stem. The root system of this plant species is well-developed and is capable of withstanding severe drought conditions. The plant is adapted to growing in rocky and mountainous areas, and it prefers well-drained soils.Light Requirements
Berkheya carlinopsis subsp. sylvicola typically prefers moderate to bright indirect light. Direct, intense sunlight may burn the foliage, so it is best to provide them with some shade during the hottest part of the day. These plants can adapt to lower light levels but may not grow as compact and full as those receiving adequate light.
Temperature Requirements
These plants prefer a warm climate, with an average temperature ranging from 65-75°F (18-24°C). It is important to avoid sudden temperature changes as this can cause stress and weaken the plant. Additionally, keep these plants away from cold drafts or frost as this can damage or even kill them.
Soil Requirements
Berkheya carlinopsis subsp. sylvicola thrives in well-draining soil that is high in organic matter. A mixture of sand, peat moss, and a good quality potting mix is suitable for these plants. Avoid overwatering and ensure proper drainage, as this plant does not tolerate waterlogged soil.
It is important to remember that these plants are native to mountainous regions and are adapted to tolerate some drought-like conditions. Therefore, it is essential to strike a balance between moist soil and not overwatering as this can lead to root rot.
Cultivation methods
Berkheya carlinopsis Welw. ex O.Hoffm. subsp. sylvicola (S.Moore) Roessler is commonly known as the Forest Berkheya and is a South African perennial herb. It grows well in full sun to semi-shade, but the ideal location is one that has dappled shade. A well-drained soil mix rich in organic matter is suitable for this plant, and it requires good airflow. Propagation can be done by seeds or cuttings. Cuttings should be taken during the growing season, and seeds should be sown in spring or autumn.
Watering needs
The Forest Berkheya has moderate water requirements. It is essential to avoid overwatering as it may cause root rot, but at the same time, it should not experience prolonged dry periods. Watering should be done when the top layer of soil feels dry to the touch. During the winter period, its watering schedule should be reduced, but it should not be allowed to dry out completely.
Fertilization
A balanced, slow-release fertilizer with an equal ratio of nitrogen (N), phosphorus (P), and potassium (K) is suitable for the Forest Berkheya. It should be applied once every two months during the growing season. Overfertilization should be avoided, as it may cause salt buildup in the soil and lead to root damage.
Pruning
The Forest Berkheya requires minimal pruning, and it is mainly for aesthetic purposes. Dying or damaged leaves should be removed to prevent the spread of disease. Pinching back the plant during the growing season will help encourage bushier growth. It is advisable to prune the plant in the early spring before new growth appears.
Propagation of Berkheya carlinopsis Welw. ex O.Hoffm. subsp. sylvicola (S.Moore) Roessler
Berkheya carlinopsis Welw. ex O.Hoffm. subsp. sylvicola (S.Moore) Roessler can be propagated through seeds, division, or stem cuttings. Each method has its own set of requirements and steps:
Propagation by Seeds
The seeds of Berkheya carlinopsis can be sown directly in the field or in a pot. The best time for sowing seeds is during the warm months of the year (spring to summer). The soil should be moist and well-drained. The seeds should be sown at a depth of 2-3mm and covered lightly with soil. Germination should occur within 10-14 days, and the seedlings can be transplanted after 6-8 weeks.
Propagation by Division
The plant can be divided in the spring or fall when the plant is dormant. Carefully remove the plant from the ground and gently separate the roots, ensuring that each division has an adequate number of shoots and roots. Replant the divisions as soon as possible into the well-drained soil. Water thoroughly to ensure the soil settles around the roots.
Propagation by Stem Cuttings
Berkheya carlinopsis can be propagated through stem cuttings taken in the spring or early summer. Take a cutting about 10cm in length and remove the leaves from the bottom two-thirds of the stem. Dip the stem into rooting hormone and plant it in a mix of perlite and peat moss. Water well and cover the pot with clear plastic. Keep the pot in a warm and bright area with indirect light. Roots should form in two to three weeks, and the cutting can be transplanted into a larger pot or directly into the field.
