Propagation of Phacelia Vallis-Mortae J. Voss
Phacelia vallis-mortae J. Voss, commonly known as Death Valley scorpionweed, is a beautiful and hardy plant endemic to the Mojave Desert of California. It is an annual plant that can grow up to 1-2 ft tall and produces lavender to purple flowers in the spring, making it a popular ornamental plant in desert gardens. Propagation of this plant can be done through various methods, including seed propagation, cuttings, and division.
Seed Propagation
Seed propagation is the most common method used to propagate Phacelia vallis-mortae J. Voss. The seeds are small and can be collected from the plant once the flowers have dried and the seed pods have turned brown. The seeds can be sown directly into the ground in the fall, or indoors in the spring before transplanting. For indoor propagation, the seeds should be sown in a well-drained potting mix and kept moist until they germinate, which usually takes about two weeks. Once the seedlings have grown a few inches tall, they can be transplanted into their permanent location outside.
Cuttings
Cuttings can also be used to propagate Phacelia vallis-mortae J. Voss, although this method is less common. To propagate through cuttings, choose a healthy stem and cut a 4-6 inch section from it. Remove the bottom leaves and dip the end of the cutting in rooting hormone. Plant the cutting in a well-drained potting mix and keep it moist until it takes root, which can take several weeks. Once the cutting has taken root, it can be transplanted outside.
Division
Division is another method used to propagate Phacelia vallis-mortae J. Voss, although it is less commonly used. The plant can be divided in the fall, once it has finished flowering and the foliage has died back. Carefully dig up the plant and divide the root ball into several sections, making sure each section has some roots intact. Replant the divided sections in their permanent location, making sure to water them well.
Overall, Phacelia vallis-mortae J. Voss is an easy plant to propagate and can be grown from seed, cuttings, or division. With proper care and maintenance, it can make a beautiful addition to any desert garden.
