Brongn. var. spiciflora (A.Rich.) Chiov.
Sageretia theezans (L.) Brongn. var. spiciflora (A.Rich.) Chiov. can be propagated through various methods such as seeds, cuttings, and layering. Propagation through seeds is relatively easy and simple, but it can take up to 25-30 days for the seeds to germinate.

Propagation through stem cuttings is a popular and efficient method for Sageretia theezans (L.) Brongn. var. spiciflora (A.Rich.) Chiov. The best time for taking cuttings is during the spring or early summer season. Cuttings should be taken from young and healthy stems from the middle to lower part of the plant. The cutting should be around 6-8 inches long and have 2-3 leaves. Cuttings can be propagated in either water or soil, with rooting hormones often used to encourage faster root growth.
Propagation through layering is another method that can also be used for Sageretia theezans (L.) Brongn. var. spiciflora (A.Rich.) Chiov. Layering involves bending a low hanging stem from the mother plant into the soil, where it will root and form a new plant with ease. This method is best conducted during spring and early summer when the plant is actively growing and capable of producing new growth. Once the new plant has taken root, it can be carefully separated from its mother plant and transplanted into a new pot.
