Pruning
Phacelia parryi Torr. var. celata Jepson & Hoover ex Jepson does not require much pruning but can benefit from deadheading. Deadhead spent flowers to encourage the plant to produce new blooms and maintain a neat appearance. Cut back any leggy stems to promote bushier growth. If the plant becomes overgrown, cut it back by one-third in the early spring before new growth emerges.
Propagation Methods for Phacelia parryi Torr. var. celata Jepson & Hoover ex Jepson
Phacelia parryi Torr. var. celata Jepson & Hoover ex Jepson is a beautiful perennial plant that is native to California, particularly the southern part of the state. If you're interested in growing this plant, you'll be pleased to know that it's relatively easy to propagate.
Propagation by Seed
The easiest and most successful way to propagate Phacelia parryi Torr. var. celata Jepson & Hoover ex Jepson is by seed. You can collect the seeds from the mature dried flowers during the summer months. The seeds should be sowed in well-draining and moist soil and kept in a warm location with plenty of sunlight. The seedlings should emerge within 2-3 weeks.
Propagation by Cuttings
While it is possible to propagate Phacelia parryi Torr. var. celata Jepson & Hoover ex Jepson through stem cuttings, it can be quite difficult and less successful than propagating through seeds. If you prefer to propagate through cuttings, make sure to take cuttings from the most robust and healthy plants. The cuttings should be treated with rooting hormone and placed in moist, well-draining soil. Place the cuttings in a warm and sunny location and keep the soil moist until roots are established.
Propagation by Division
Another possible way to propagate Phacelia parryi Torr. var. celata Jepson & Hoover ex Jepson is by division. This requires digging up an established plant in the early spring and dividing the plant into several sections, making sure each section has healthy roots and foliage. Each divided section should then be planted in a well-draining soil mix, watered thoroughly, and kept in a warm and sunny location until they are established.
By following these methods, you can propagate Phacelia parryi Torr. var. celata Jepson & Hoover ex Jepson and enjoy the beautiful, blue-purple flowers all year round.
