Propagation of Epilobium parviflorum Schreb.
Epilobium parviflorum Schreb. can be propagated through seeds, division, or stem cuttings.
Seed Propagation
The easiest way to propagate Epilobium parviflorum Schreb. is through seeds. Collect the seeds in the fall when the seed pods have turned brown. Plant the seeds in the spring as soon as the ground can be worked. Sow the seeds on the surface of the soil and cover lightly with soil. Keep the soil moist until the seeds germinate, which can take up to four weeks. Once the plants have developed their true leaves, transplant them into individual pots or into the garden.
Division Propagation
Epilobium parviflorum Schreb. can be propagated through division in the early spring. Dig up the plant and separate the roots into sections, making sure each section has a healthy root system and preferably a few stems. Replant each section in a new location, making sure the roots are covered with soil and the top of the root ball sits just below the surface of the soil. Water thoroughly after planting.
Stem Cutting Propagation
Epilobium parviflorum Schreb. can also be propagated through stem cuttings. Take cuttings in the early summer when the plant is actively growing. Cut a 4- to 6-inch section of stem that has some new growth and remove the lower leaves. Dip the cut end in rooting hormone and plant it in a pot filled with a mixture of perlite and peat moss. Keep the soil moist and place the pot in a bright location but out of direct sunlight. Once the cutting has developed roots and is showing new growth, transplant it into a larger pot or into the garden.
