This plant is known for its beautiful foliage and delicate flowers, which make it a great addition to any garden or indoor space. When it comes to propagating Plectranthus venteri, there are a few different methods that can be used, including seed propagation, stem cutting propagation, and division propagation.
Seed Propagation

Stem Cutting Propagation
Another popular method for propagating Plectranthus venteri is stem cutting propagation. To do this, take a cutting from a mature plant in the spring or summer and remove all of the lower leaves.

Once the roots have formed, you can transplant the new plant to a larger pot or directly into your garden.
Division Propagation
Division propagation is a third method that can be used to propagate Plectranthus venteri. To do this, carefully remove a mature plant from its pot or garden bed and gently separate the root ball into smaller sections. Each section should have its own stem and root system. Once divided, the new plants can be planted in their own pots or directly into the garden.
Regardless of the propagation method you choose, it is important to keep your new plants in a well-lit area and to provide them with plenty of water and nutrients to help them grow strong and healthy.
