 - Growth Characteristics: It primarily grows at low water levels; its initial leaves are submerged, while it develops floating leaves in shallow water.

Propagation Methods:
 - Seed Propagation: Mature seeds can be collected and sown on the water surface or in moist soil.
 - Root Division: Propagation by dividing the plant's roots is also a common method.

Cultivation Methods:
 - Water Quality and Temperature Management: Maintain clean water and consistently keep the temperature at an appropriate level.
 - Light Control: It is recommended to select a location that allows for sufficient sunlight.
 - Nutrient Supply: Supply an appropriate amount of nutrients to the water to ensure the plant grows well. Use in Gardens:

Sophora can be planted along the edges of water tanks or ponds to enhance the landscape. Its small, neat leaves make it an attractive element for landscaping.

Important Pests and Control Methods:
 - Diseases: Generally, there are no major diseases, but mold problems may occur if water quality is poor. It is important to change the water periodically.
 - Pests: Pest damage is rare, but infrequent damage from aphids or snails may occur. Physical removal methods can be used, or safe insecticides can be applied.

While it is generally relatively easy to care for, maintaining appropriate environmental conditions is important for its growth.
