How can one effectively cultivate a garden with propagating purple passion plants?

To effectively cultivate a garden with propagating purple passion plants, you can start by taking stem cuttings from a healthy plant and rooting them in water or soil. Make sure the cuttings have at least one node and remove any leaves near the bottom. Keep the cuttings in a warm, humid environment and water them regularly. Once roots have formed, transplant the cuttings into well-draining soil and place them in a sunny spot. Water the plants regularly and fertilize them occasionally to promote healthy growth.
