Propagation of Gerardia edwardsiana (Pennell) Pennell
Gerardia edwardsiana (Pennell) Pennell, commonly known as Edward's gerardia or Edward's false foxglove, is a perennial plant native to the southeastern United States. This plant species typically grows in dry and sandy soils, and blooms from July to October. Propagation of Gerardia edwardsiana can be done using the following methods.
Seed Propagation
Seed propagation is a common method for propagating Gerardia edwardsiana. One can collect the seeds from the mature seed capsules after flowering. To ensure successful germination, it is essential to collect seeds while they are fresh, dry, and dark in color. The seeds should be sown in well-draining soil, which is kept moist. Once the seedlings are large enough to handle, they can be transplanted to containers or directly into the garden in their permanent location.
Stem Cutting Propagation
Propagation of Gerardia edwardsiana can be done through stem cuttings. Cutting is usually done when the plant is actively growing, typically during spring or early summer. Take the cuttings of about 5 to 8 cm long from the terminal end of the stem. Remove the lower leaves, dip the cuttings in rooting hormone and plant them in a well-draining soil mix. Place the pots in a warm location that receives bright, indirect light, and keep the soil consistently moist.
Division
Dividing mature plants is another way to propagate Gerardia edwardsiana. This method is best done in the spring, when the plant is starting to grow after dormancy. Dig up the parent plant and remove the soil from its roots. With a sharp, clean knife, divide the plant into sections, making sure each section has its roots and foliage. Replant the divided sections immediately in their permanent location, making sure the soil is well-draining and kept moist.
Final thoughts
Gerardia edwardsiana is relatively easy to propagate using the above methods. It is essential to handle the plant with care during propagation and provide the necessary growing conditions to ensure its successful establishment. Propagation should be done during the plant's active growth period for best chances of success.
