Centrosema virginianum, commonly known as the Spurred Butterfly Pea, is a versatile plant that can be propagated by both sexual and asexual methods.

Whether you want to expand your garden or share its beauty with others, here are some propagation methods to try:

Sexual Reproduction:

One of the most common and straightforward ways to propagate the Spurred Butterfly Pea is through seed germination. Collect mature seeds from the plant and store them in a dry, cool area until you are ready to plant them.

In early spring, sow the seeds into a well-draining potting mix and cover it with a thin layer of soil. Keep the soil damp throughout the germination period, which should take about two to three weeks.

Once germinated, move the young plants into larger containers and then transplant them into the garden in the spring after the last frost. Asexual Reproduction:

If you want faster results, you can try propagating the Spurred Butterfly Pea asexually.

One of the most common asexual methods of propagation is by taking stem cuttings. Choose a healthy stem and cut it with a sharp, clean pair of scissors or pruning shears.

Make the cut below a node and ensure that the cutting is at least four inches (10 cm) long. Remove any leaves from the bottom section of the cutting and dip it into a rooting hormone powder.

Plant the cutting into a well-draining potting mix and keep it damp in a warm and bright location. Once the cutting has rooted, move it into a larger container and then transplant it into the garden.


Another asexual method of propagation is division. Dig up the plant in the spring or fall and using a sharp knife, separate the plant into individual sections, ensuring that each section has roots and shoots.

Trim any damaged or dead roots and then transplant the sections into containers or garden beds.
