Propagation methods for Penstemon antirrhinoides Benth.
Penstemon antirrhinoides Benth., commonly known as snapdragon penstemon, is a beautiful flowering plant native to North America. The plant is quite hardy and can tolerate a wide range of growing conditions. Propagating snapdragon penstemon can be done by seed and stem cuttings.
Seed propagation
Propagation through seeds is the most common method of growing snapdragon penstemon. The best time to sow the seeds is in fall or early spring, in well-drained soil. The seeds should be sown in a depth of 1/8 inch and covered with soil. After sowing, the soil should be kept moist until germination takes place, which can take up to 3 to 4 weeks. The ideal temperature for germinating snapdragon penstemon seeds is around 60°F to 70°F (15.5°C to 21°C).
Stem cutting propagation
Propagation of snapdragon penstemon through stem cuttings can be done any time from spring to the end of summer when the plant is actively growing. The cuttings should be taken from mature and healthy stems, which are around 3 to 5 inches long. The cutting should have a minimum of three leaves and should be cut at a 45-degree angle. The bottom leaves should be removed, leaving only two or three leaves at the top. The cuttings should then be dipped in rooting hormone and planted in a mix of well-drained soil and perlite. The soil should be kept moist, and the cuttings should be placed in a shaded, warm location. It will take around 6 to 8 weeks for root development to occur.
Once the roots have developed, the new plants can be transplanted into their permanent location. Propagating snapdragon penstemon through stem cuttings can be an excellent way to produce multiple plants quickly.
