Chrysothemis pulchella is a perennial herb that grows up to 60 cm tall. Its leaves are dark green, oval-shaped, and grow in opposite pairs along the stem. The flowers, which bloom in summer and fall, are a vibrant yellow and arranged in clusters on the tips of long stems. Each flower has a tubular shape, with five petals fused at the base, forming a shrimp-like structure. The plant prefers a warm and humid climate and can be grown in partial shade or full sunlight.Light Requirements
Chrysothemis pulchella requires bright, indirect light to grow and thrive. It can tolerate some direct sunlight, but too much can burn the leaves.
Temperature Requirements
This plant grows best in temperatures between 60-75°F (15-24°C). It can tolerate slightly cooler temperatures, but it is sensitive to cold drafts and should be kept away from doors or windows that may let in cold air.
Soil Requirements
Chrysothemis pulchella requires well-draining soil that is rich in organic matter. It prefers slightly acidic to neutral soil with a pH between 6.0-7.0. It is important to allow the soil to dry out slightly between waterings to prevent root rot.
Cultivation Methods
The Chrysothemis pulchella plant can be grown from seeds, which should be sown in fertile, well-draining soil. The plant needs full sunlight exposure to thrive, making it suitable for outdoor cultivation. The seeds germinate continuously throughout the year, with a faster rate during the rainy season. To promote growth, ensure that the soil is kept moist, and maintain a temperature range of 20-25 degrees Celsius. The plant reaches a maximum height of 30 cm and spreads on the ground to form a mat.
Watering Needs
Chrysothemis pulchella plants need to be watered regularly to maintain moisture levels in the soil. However, avoid overwatering as it can lead to root rot. The best way to water this plant is by ensuring that the soil is damp to the touch, and watering it when the top inch of soil is dry. During the rainy season, the plant's natural water source is sufficient, and minimal watering is required.
Fertilization
Regular fertilization is beneficial to ensure that your Chrysothemis pulchella plant remains healthy. Use a balanced fertilizer, preferably one that is high in phosphorus, and apply it during the plant's growing season. To avoid over-fertilization, use slow-release granular fertilizer or liquid fertilizers at half the recommended strength. Feed the plant every eight weeks during the growing season to promote optimal growth and maintain a healthy appearance.
Pruning
Pruning should be done primarily to control the plant's size and maintain its appearance. The Chrysothemis pulchella plant does not require frequent pruning since it has a low-growing habit. However, to remove any dead or faded leaves, you can use a pair of sharp scissors or pruning shears. This will encourage new growth and ensure the plant remains healthy and vibrant.
Propagation of Chrysothemis Pulchella
Chrysothemis Pulchella can be propagated through a few different methods:
Seed Propagation
One way to propagate Chrysothemis Pulchella is through seed propagation. The seeds of this plant can be sown in a well-draining potting mix. The seeds should be sown shallowly and covered in a thin layer of soil. The pot can be watered lightly and set in a location where it can receive bright, indirect sunlight. Germination usually occurs within a few weeks. When the seedlings have grown large enough, they can be transplanted into individual pots and grown on until they are large enough to be planted in the garden.
Division
Another way to propagate Chrysothemis Pulchella is through division. This method involves dividing the existing plant into smaller sections and replanting them. To do this, the plant should be lifted out of the ground or pot and the roots gently teased apart. Each section should have a healthy amount of roots attached. The sections can then be planted in their new location. This method is best done in the spring or fall.
Stem Cuttings
Chrysothemis Pulchella can also be propagated through stem cuttings. This method involves taking a cutting of the stem 7-10 cm long with a few leaves attached. The bottom of the cutting should be dipped in rooting hormone and planted in a well-draining potting mix. The pot should be kept moist and set in a location where it can receive bright, indirect sunlight. The cutting should root within a few weeks, and once it has rooted, it can be transplanted into its permanent location.

Pests
While Chrysothemis pulchella is generally not a target for pests, some pests might still affect this plant. Here are some common pests that may cause problems:
Spider Mites
Spider mites are tiny arthropods that spin webs on the leaves and cause discoloration and distortion of the leaves. To manage spider mites, wash the leaves thoroughly with water and spray with an insecticidal soap. You can also introduce predatory mites to control their population.
Aphids
Aphids are small insects that feed on the sap of the plant, causing yellowing and deformation of the leaves. To manage aphids, use a strong spray of water to knock them off the plant. You can also introduce beneficial insects like ladybugs or lacewings to control their population.
