Fertilizer: Keckiella antirrhinoides var. microphylla does not require regular fertilization, as excessive nutrients can lead to leggy growth and reduced flowering. However, a light application of a balanced fertilizer in early spring may help promote vigorous growth and blooming.
Propagation: This plant can be propagated by seed or by stem cuttings taken in late spring or early summer. Seed can be started indoors and transplanted after the last frost, or sown directly in the garden in late fall. Cuttings should be taken from non-flowering shoots and rooted in a well-draining rooting medium under bright but indirect light.
Cultivation
Keckiella antirrhinoides (Benth.) Straw var. microphylla (Gray) N. Holmgren, commonly known as the Little-leaved Penstemon, is a drought-tolerant shrub that is native to California and Oregon. It is easy to grow and requires minimal maintenance, making it an excellent choice for novice gardeners or those with limited time to devote to gardening.
The plant prefers to grow in well-drained soil and full sun to partial shade. It is adaptable to most soil types, including sandy, loamy, and clay soils.
Watering Needs
Keckiella antirrhinoides var. microphylla is a drought-tolerant plant, but like most plants, it requires regular watering until it establishes a strong root system. After that, watering can be reduced to once or twice a month, depending on local weather conditions. If the plant shows signs of wilt or stress, increase the frequency of watering until it recovers.
During hot, dry weather, or prolonged drought, the shrub may require additional watering, either with a hose or irrigation system. However, be cautious of over-watering, as too much water can cause root rot and other fungal diseases.
Fertilization
Little-leaved Penstemon does not require heavy fertilization, as excessive nutrients can stimulate leaf growth at the expense of flowers. However, an annual application of a balanced fertilizer, such as 10-10-10, in the spring can enhance blooming and growth. Follow package instructions and avoid over-fertilization, which can harm the plant.
Pruning
Pruning is not necessary for Keckiella antirrhinoides var. microphylla, but it can help maintain the plant's health and shape. Dead or damaged branches should be removed as soon as possible to prevent disease or insect infestations.
To control size or shape, prune lightly in the spring before new growth starts. Avoid pruning too much, as this can reduce blooming and the plant's overall health. Generally, the plant responds well to light pruning or shearing, which can promote bushier growth and more flowers.
Propagation of Keckiella antirrhinoides
Keckiella antirrhinoides (Benth.) Straw var. microphylla (Gray) N. Holmgren, commonly known as the small-leaved bush snapdragon, belongs to the family Plantaginaceae. This plant is native to North America and is mainly found in the western United States. The propagation of Keckiella antirrhinoides can be achieved through various methods.
Seed Propagation
Keckiella antirrhinoides can be propagated through seeds. The seeds can be collected from the mature seed pods of the plant. Once the seed pods have matured, they will burst open, revealing the seeds. The seeds can be collected and stored in a cool, dry place until they are ready to be sown.
To sow the seeds, a well-draining potting mix should be used. The seeds should be sown on the surface of the potting mix and lightly covered with soil. Water the potting mix well and place the container in a warm, bright area. The seeds should germinate within a couple of weeks.
Cutting Propagation
Keckiella antirrhinoides can also be propagated through cuttings. Softwood cuttings can be taken from the plant in the spring or early summer when the plant is actively growing. The cuttings should be 4-6 inches in length and should be taken from healthy, disease-free plants.
The cuttings should be dipped in a rooting hormone and placed in a well-draining potting mix. The container should be placed in a warm, humid area with bright, indirect light. The cuttings should root within a few weeks and can be transplanted once they have established roots.
Division
Keckiella antirrhinoides can also be propagated through division. This method works best for mature plants that have a well-established root system. The plant should be dug up and the root ball should be carefully divided into smaller sections. Each section should have some foliage and a portion of the root system.
The divided sections should be replanted in a well-draining potting mix and watered well. They should be placed in an area with bright, indirect light and kept moist until new growth appears.
