Temperature requirements
This plant type prefers warmer temperatures of at least 18°C to 35°C (65°F to 95°F) for optimal growth. In colder temperatures, it may become dormant or die. It can tolerate high humidity levels but does not thrive in cold and frosty conditions.
Soil requirements
Cassia polytricha Brenan var. pulchella Brenan prefers well-draining soil with pH levels ranging from slightly acidic to neutral (6.0 to 7.5). It tolerates poor soil conditions but prefers rich, loamy soil. It is recommended to use organic matter such as compost or peat moss to improve soil structure. Overwatering should be avoided as it may lead to root rot.
Cultivation
Cassia polytricha Brenan var. pulchella Brenan is a beautiful and exotic plant that requires special care and attention. This plant is native to Africa, and it requires a warm and humid environment to thrive. It grows well in well-drained soil that contains a lot of organic matter.
The plant requires adequate protection from direct sunlight, especially during the hot parts of the day. It is recommended to place it in a partially shaded area where it can receive some sunlight but not too much. It can also be grown indoors in a bright room.
Watering Needs
Cassia polytricha Brenan var. pulchella Brenan requires moderate watering. The soil should be kept moist but not too wet. Overwatering can cause root rot and other fungal diseases, so it should be avoided. It is essential to use well-draining soil and pots with adequate drainage holes.
The plant needs more frequent watering during the hotter months of the year and less during the colder months. It is also essential to avoid letting the soil completely dry out, as this can cause severe stress to the plant.
Fertilization
Cassia polytricha Brenan var. pulchella Brenan requires regular fertilization to thrive. It is recommended to use a balanced fertilizer every two weeks during the growing season. The fertilizer should be high in nitrogen to promote healthy foliage growth. During the dormant season, the plant does not require any fertilization.

Propagation of Cassia polytricha Brenan var. pulchella Brenan
The Cassia polytricha Brenan var. pulchella Brenan, commonly known as the coffee cassia or brush cassia, is a small, evergreen shrub that is native to Africa. It is often cultivated as an ornamental plant due to its showy, yellow flowers.
Propagation of this plant can be done through different methods, such as:
Seed propagation
Seeds collected from the pods or the fruit should be sown when they are fresh. The seeds may germinate within four to six weeks after sowing. To propagate through seed, follow these steps:
- Soak the seeds in warm water for a few hours.
- Prepare the soil mixture consisting of equal parts of sand, perlite, and peat moss.
- Place the seed on top of the soil mixture and press down gently.
- Water the seed and cover it slightly with soil.
- Place a plastic bag over the pot to maintain the humidity and place it in a warm place with indirect sunlight.
- A few weeks later, seeds will sprout.
Cuttings propagation
Cuttings from semi-ripe wood can be propagated from the parent plant. Follow these steps to propagate through cuttings:
- Take a 4 to 6-inch cutting from the current season's growth.
- Remove the lower leaves of the cutting.
- Dip the cutting in rooting hormone powder.
- Prepare a mixture of perlite and peat moss and wet it.
- Make a hole in the soil mixture and insert the cutting in it.
- Place the pot under indirect sunlight and maintain the humidity by covering it with a plastic bag.
- Roots will develop within three to four weeks.
Whichever method you choose, be sure to keep the soil moist, but not waterlogged, and keep the temperature warm, but not too hot. Once the plants have established roots, you can transplant them into individual containers or outdoors in well-draining, rich soil.
