It might be a bit of a challenge since not many folks sell the seeds of this plant, but I'm here to help! You can collect the seeds by waiting for the flowers to turn brown, then gently cutting the stems and placing them in a paper bag to dry. After about a week, give the bag a good shake to release the seeds. The seeds look like small black pepper spots, so you can easily spot them.Then, sow the seeds and place the plant in a cool, well-drained spot. Wait for the seeds to grow roots, and then you can move them into a container or wherever you want to grow them permanently.
