Propagation of Chaenactis glabriuscula DC. var. tenuifolia (Nutt.) Hall
Chaenactis glabriuscula DC. var. tenuifolia (Nutt.) Hall can be propagated through several methods which includes:
Seed Propagation
Propagation of Chaenactis glabriuscula DC. var. tenuifolia (Nutt.) Hall is easiest through seeds. The seed heads are harvested in late summer when their plumes turn white. The seed heads should be dry, but not so dry that the plumes come off easily. The plumes can be removed by rubbing the seed head on a screen, or by shaking it in a paper bag. Seeds should be stored in a cool, dry place until needed. The seeds should be planted in the fall or early spring. Shallow planting is recommended as the seeds require light for germination. Seeds should be covered with coarse sand or fine gravel to ensure good seed-to-soil contact. Germination can take several weeks to several months, so patience is necessary.
Cutting Propagation
Chaenactis glabriuscula DC. var. tenuifolia (Nutt.) Hall can also be propagated vegetatively with stem cuttings. Take a cutting that is 4-6 inches long during the plant's active growth period, which is late spring to early summer. The cutting can be dipped in rooting hormone and planted in sterile potting soil. Place in bright, indirect light and keep the soil moist until roots develop. Transplant the cutting to a larger pot or outdoors once it has developed a good root system.
