Propagation Methods for Hieracium gracile Hook. var. detonsum (Gray) Gray
Hieracium gracile Hook. var. detonsum (Gray) Gray, commonly known as the slender hawkweed, is a herbaceous perennial plant that is native to North America. It grows up to 40cm in height and produces yellow, daisy-like flowers in summer.
If you desire to propagate this plant species, here are some propagation methods to consider:
Propagation via Seeds
The most common method of propagating Hieracium gracile is through seeds. You have to collect fresh seeds from the plant in the autumn, then store them in a dry and dark location until planting time the following spring.
When spring arrives, spread the seeds over well-draining soil and cover them with a layer of compost. Lightly press the soil to make sure it is packed firmly around the seeds, then water immediately. Keep the soil moist, but not too wet, and the seeds should germinate within two to three weeks.
Propagation via Division
You can propagate Hieracium gracile by dividing its rhizomes. Do this in the spring, or after the plant has finished flowering. Carefully dig out the plant’s roots by using a garden fork, and then separate the roots and rhizomes by cutting them neatly into segments.
Each segment must have at least two to three buds. Transplant the divided segments into individual pots or directly in the garden bed if the soil is loose. Provide moderate watering and good drainage, and the new transplants should establish within a couple of weeks.
Propagation via Cuttings
You can get new Hieracium gracile plants from stem cuttings too. Take the clones in spring or early summer, and use sharp, clean shears to make clean cuts at a 45-degree angle. Make sure each cutting is at least 5cm long and has one or two leaves remaining.
Dip the cuttings into rooting hormone and plant them in a well-draining potting mix. Firm the potting mix around the cuttings with your fingers, then water lightly. Place the cuttings in an area of bright, indirect light, and make sure to keep the soil moist but not too wet. The cuttings should grow roots in about six to eight weeks and be ready for transplanting.
