Propagation of Aquilegia flavescens S. Wats. var. flavescens
Aquilegia flavescens S. Wats. var. flavescens, commonly known as yellow columbine, is a herbaceous perennial plant that belongs to the Ranunculaceae family. Its attractive yellow flowers make it a popular choice for gardeners. Propagation of this plant can be done by using various methods including seeds, division, and cuttings.
Seeds
The most common method of propagating Aquilegia flavescens is through the use of seeds. After the plant has finished flowering, it will produce seed pods that can be harvested. Once the seed pods are dry and brown, they can be collected and stored in a cool and dry place until ready to be planted. Sow the seeds in the spring, and cover lightly with soil. The seeds will germinate in about 2-3 weeks, and can be transplanted once they have developed a few leaves.
Division
Another method of propagation is through division. This is best done in the spring or fall. Dig up the plant and gently separate the roots into smaller sections, ensuring each section has a few stems and roots. Replant the divided sections into new soil in a location with partial shade, keeping the soil moist. The newly planted sections will establish themselves within a few weeks, and will continue to grow and flower in subsequent years.
Cuttings
Aquilegia flavescens can also be propagated by taking cuttings. This method is best done during the growing season, when new shoots are present. Select a healthy shoot and cut off a 3-4 inch piece. Remove the lower leaves and place the cutting in a container of moist, well-draining soil. Cover the container with plastic to maintain high humidity, and place it in a shaded area. The cutting will develop roots in a few weeks, and can then be transplanted into individual pots.
