Propagation of Aureolaria pedicularia (L.) Raf. var. pedicularia
Aureolaria pedicularia (L.) Raf. var. pedicularia, commonly known as Fern-leaved False Foxglove, can be propagated by both seeds and division.
Propagation by seeds
The seeds of Fern-leaved False Foxglove require stratification to germinate. The best time to sow the seeds is in the fall, although they can also be sown in the spring. The seeds require light for germination, so they should be sown on the surface of the soil or lightly pressed into the soil. The ideal soil temperature for germination is between 68°F and 72°F. Germination can take anywhere from 3 to 6 weeks. Once the seedlings have grown to a size where they can safely be handled, they can be transplanted into their permanent location.
Propagation by division
Fern-leaved False Foxglove can also be propagated by division. The best time for division is in the spring, just as new growth is beginning. Carefully dig up the plant and gently separate the clump into smaller sections. Each section should have a good root system and several stems. Replant the divisions in their permanent location, and water them well.
