Taming the Wild Heart: Propagating Roundleaf Cancerwort (Kickxia spuria)
Roundleaf Cancerwort (Kickxia spuria) may not roll off the tongue as easily as “sunflower” or “rose,” but this charming little plant, with its delicate yellow flowers and heart-shaped leaves, deserves a spot in any wildflower enthusiast’s garden. Don’t let its somewhat unfortunate name deter you – this annual is a delight to grow and with a little patience, you can enjoy its unique beauty year after year.
Often found gracing meadows and roadsides, Roundleaf Cancerwort is surprisingly easy to propagate, both from seed and cuttings. So, if you’ve stumbled upon this post after encountering this wild beauty in its natural habitat (or perhaps you’re looking to expand your existing patch), let’s dive into the techniques for successfully propagating Kickxia spuria.
From Seed: A Story of Patience and Reward
Seed Collection: Keep an eye out for the small, black seeds that develop in capsules as the plant matures in late summer. They’re ripe for the taking when the capsules turn brown and start to split open.
Sowing: You can sow these tiny seeds directly into your garden in the fall. Choose a sunny spot with well-drained soil and sprinkle the seeds lightly on the surface, barely pressing them in. Nature will take its course, and you’ll be greeted with new seedlings in the spring.
- Indoor Sowing (Optional): For a head start, sow seeds indoors 6-8 weeks before the last frost. Use a seed starting mix, maintain consistent moisture, and provide plenty of sunlight. Transplant the seedlings outdoors after the danger of frost has passed, spacing them about 12 inches apart.
Taking Cuttings: A Faster Route to New Growth
The Right Time: Early summer is the ideal time to take cuttings, just as the plant starts to flourish.
Making the Cut: Using a sharp, clean knife or pair of scissors, take 3-4 inch cuttings from healthy stems, making the cut just below a leaf node.
Preparing the Cuttings: Remove the lower leaves from the cutting, leaving only a few at the top. This encourages root development.
Rooting Hormone (Optional): Dipping the cut end in rooting hormone can speed up the process, but it’s not strictly necessary.
Planting the Cuttings: Plant the cuttings in small pots filled with a well-draining potting mix. Keep the soil consistently moist and place the pots in a bright location, out of direct sunlight.
- Transplanting: Once the cuttings have developed a strong root system (usually within a few weeks), they’re ready to be transplanted into your garden or larger containers.
Caring for Your Roundleaf Cancerwort
Kickxia spuria is remarkably low-maintenance. It prefers full sun to partial shade and well-drained soil. Water regularly until established, then allow the soil to dry out slightly between waterings. Deadheading spent flowers can encourage more blooms, but feel free to let some go to seed for next year’s crop.
With a little effort and a lot of love, you can enjoy the delicate charm of Roundleaf Cancerwort year after year. So, why not invite this captivating wildflower into your garden and discover the joy of propagating this unique and often-overlooked beauty?
