Growth Conditions for Millettia klainei Dunn var. floribunda Pellegr.
Light: Millettia klainei Dunn var. floribunda Pellegr. requires bright, indirect light for proper growth. It is best to place the plant near a north or east-facing window where it can receive filtered sunlight throughout the day.
Temperature: The plant prefers warm temperatures between 18°C to 27°C (65°F to 80°F). It is important to avoid exposing the plant to temperatures below 15°C (59°F) as it can lead to damage and slower growth.
Humidity: Millettia klainei Dunn var. floribunda Pellegr. prefers high humidity levels. The best way to achieve this is by placing the plant in a room with a humidifier or by placing a tray of water near the plant. Regular misting can also be done to maintain the humidity level around the plant.
Soil: The ideal soil for Millettia klainei Dunn var. floribunda Pellegr. is a well-draining, aerated potting mix with a slightly acidic pH between 6.0 to 6.5. The soil should be kept moist but not waterlogged as this can lead to root rot.
Fertilizer: The plant requires regular fertilization during the growing season (spring and summer). A balanced, water-soluble fertilizer with a 20-20-20 ratio can be used every 2-3 weeks. It is important to reduce the frequency of fertilization during the fall and winter months.
Water: Millettia klainei Dunn var. floribunda Pellegr. requires regular watering, especially during the summer months. The soil should be kept evenly moist but not waterlogged as this can lead to root rot. It is important to reduce watering during the fall and winter months to avoid overwatering.
Propagation: The plant can be propagated through stem cuttings taken during the spring and summer months. The cuttings should be placed in a well-draining potting mix and kept in a warm, humid location until roots develop.
Cultivation Methods
Millettia klainei Dunn var. floribunda Pellegr. thrives well under tropical and subtropical climates. It grows best in well-draining, fertile soils, enriched with organic matter. The plant needs adequate sunlight exposure, along with proper watering and fertilization practices.
The recommended method of propagation for Millettia klainei Dunn var. floribunda Pellegr. is from seedlings or stem cuttings. Plant the cuttings or seedlings at a depth that is twice the size of its root ball. Ensure proper spacing during planting. The plant does well in a sheltered environment and may require staking to support the weight of its heavy branches.
Watering Needs
Millettia klainei Dunn var. floribunda Pellegr. requires moderate watering. The plant should get enough water to keep the soil moist but not waterlogged. Water the plant deeply and allow the soil to dry out slightly before the next watering. During the growing season, water the plant more frequently.
The plant needs less water during winter when it becomes dormant. However, do not allow the soil to completely dry out, as this may cause the plant to die.
Fertilization
Millettia klainei Dunn var. floribunda Pellegr. requires proper fertilization to thrive. Use a balanced fertilizer that has equal amounts of phosphorus, potassium, and nitrogen. Apply the fertilizer in early spring before new growth begins and again in late summer after the plant has finished flowering.
To avoid over-fertilizing the plant, make sure to follow the instructions on the fertilizer package. Apply the fertilizer around the drip line of the plant and water it in thoroughly.
Pruning
Millettia klainei Dunn var. floribunda Pellegr. does not require extensive pruning but requires regular maintenance. Prune the plant regularly to remove dead or damaged branches.
Prune the plant after flowering to encourage more blooms for the next season. Cut back the branches to a length that is slightly above the next leaf node. Make the cut at a 45-degree angle.
Do not prune more than one-third of the plant at a time. Pruning the plant in the fall or early winter may remove the dormant flower buds and reduce flowering.
Propagation of Millettia klainei Dunn var. floribunda Pellegr.
Millettia klainei Dunn var. floribunda Pellegr., commonly known as the Chinese pearl-bloom, is a leguminous plant species that is native to southwest and central China. It is a valuable ornamental plant due to its beautiful flowers. Propagation of this plant can be done through several methods, including seed propagation and vegetative propagation.
Seed Propagation

Seeds take around 15-20 days to germinate, and it is recommended to transplant the seedlings when they have two to three leaves.
Vegetative Propagation
Another method of propagation for Millettia klainei Dunn var. floribunda Pellegr. is vegetative propagation. It involves taking cuttings from mature plants. Cuttings should be about 10-15 cm in length and should be taken in the spring or early summer. The cuttings should be dipped in rooting hormone and placed in a well-draining mix of sand and peat moss. They should be kept moist and in a warm environment with high humidity until roots develop, which usually takes around four to six weeks. Once roots have formed, the cuttings can be transplanted into the ground or larger containers.
