Propagation of Hutchinsia calycina Steph. ex Willd. var. americana Regel & Herder
Hutchinsia calycina Steph. ex Willd. var. americana Regel & Herder can be propagated by using seeds or cuttings.
Propagation by Seeds
The seeds of Hutchinsia calycina Steph. ex Willd. var. americana can be collected in early summer when the seedpods turn brown. The collected seeds should be dried and stored in a cool and dry place until they are needed.
When propagating through seeds, the first step is to prepare the soil mix. The soil mix should be light and well-draining. Sow the seeds on the surface of the soil mix and lightly cover with a layer of the soil mix. Keep the soil moist but not waterlogged. The seeds will germinate in two to four weeks.
When the seedlings have grown their second set of true leaves, they can be transplanted into individual pots filled with a soil mix. Keep the seedlings in a cool and bright place until they are large enough to be transplanted into their permanent locations.
Propagation by Cuttings
Hutchinsia calycina Steph. ex Willd. var. americana can also be propagated through cuttings. Take cuttings in late spring or early summer from the tips of healthy and non-flowering stems. The cuttings should be approximately 4-5 inches long and have at least one set of leaves.
Remove the leaves from the bottom one-third of the cutting and dip the cut end into a rooting hormone. Plant the cuttings in a moist soil mix and cover with a plastic bag to create a humid environment. Place the cutting in a bright but shaded location. The cuttings will root in 2-3 weeks.
Once the cuttings have rooted, they can be transplanted into individual pots filled with a soil mix. Keep the young plants in a cool and bright location until they are large enough to be transplanted into their permanent locations.
