Propagation by Seeds
Seeds of Boechera fendleri (S. Wats.) W.A. Weber var. spatifolia (Rydb.) W.A. Weber can be collected from the parent plant when the seedpods have turned brown and the seeds have matured. After collecting, the seeds can be stored in cool and dry conditions until ready to be sown.

Lightly press down on the seeds to ensure they are making contact with the soil and mist the soil with water. Maintain the soil moisture and place the pot in a bright, but not direct, sunlight. The seeds will take approximately three weeks to germinate.
Propagation by Root Cuttings
Root cuttings can be taken from a healthy parent plant during its dormant season. Using a clean and sharp knife, cut a 2-3 inch piece of root from the parent plant. Ensure the cutting has at least one bud. Fill a container with a well-draining potting mix and moisten it. Plant the root cutting vertically in the mix with the bud pointing upwards. Keep the soil moist and in a warm, bright area. The roots will develop within several weeks.
Propagation by Stem Cuttings
Stem cuttings can be taken from a healthy parent plant during its growing season. Cut a 4-6 inches long stem from the parent plant. Ensure that the cutting has at least 3-4 leaves and no flowers. Remove the lower leaves and insert the cuttings into a well-draining potting mix. Water thoroughly and cover with plastic to maintain high humidity. Keep the soil moist and in a warm, bright area. Roots will develop within 4-6 weeks.
