Propagation of Polemonium lindleyi Wherry
There are several methods for propagating Polemonium lindleyi Wherry, including seed propagation, division, and stem cuttings. The following paragraphs describe each method in detail:
Seed Propagation
Propagation of Polemonium lindleyi Wherry by seeds is relatively easy. Collect the seeds in the fall when the seed capsules turn brown. Spread them out to dry in a warm, dry place for a week. After the drying period, store them in a cool, dry place. In the spring, you can sow the seeds directly outdoors where the plant is intended to grow. Alternatively, plant the seeds in a seed tray or small pots inside four to six weeks before the last frost. The seeds will germinate in one to three months and can be transplanted outdoors after the last frost.
Division
Division is another propagation method that can be used to propagate Polemonium lindleyi Wherry. The best time to divide the plant is in the early spring before new growth starts or in the fall after the plant has gone dormant. To divide the plant, carefully remove it from the ground and divide it into several sections, making sure that each section has roots and shoots. Replant each section in well-drained soil and keep it moist until new growth appears.
Stem Cuttings
Stem cuttings can also be used to propagate Polemonium lindleyi Wherry. Take cuttings from new growth in the spring or early summer. Cut a stem that is 3-4 inches long just below a node. Remove all the leaves from the bottom half of the cutting and dip it in rooting hormone. Plant the cutting in a small pot filled with well-draining soil and keep it moist. After a few weeks, the cutting should have rooted and can be transplanted outdoors.
