Propagation methods for Sphaeralcea rusbyi Gray ssp. gilensis Kearney
Sphaeralcea rusbyi Gray ssp. gilensis Kearney, commonly known as Gilia Globe-mallow, is a drought-tolerant perennial that is native to the southwestern United States. Propagation of this plant can be done through both seed and vegetative methods.
Seed propagation
The easiest and most common method of propagation for Sphaeralcea rusbyi Gray ssp. gilensis Kearney is through seed. The seeds should be collected from mature plants once the seedpods have dried and started to split open. The seeds should be thoroughly cleaned and then sown in a well-draining soil mix in the fall or early spring. The seeds should be pressed into the soil but not covered as they require light to germinate. The soil should be kept moist until the seeds have germinated, which can take up to two weeks. Once the seedlings have developed their second set of true leaves, they can be transplanted into individual pots or directly into the ground.
Vegetative propagation
Vegetative propagation of Sphaeralcea rusbyi Gray ssp. gilensis Kearney can be done through stem cuttings. It is best to take cuttings in late spring or early summer when the plant is actively growing. The cuttings should be approximately 4-6 inches long and should be taken from healthy, non-flowering stems. The bottom inch of the cutting should be dipped in rooting hormone and then planted in a well-draining soil mix. The cutting should be kept moist and in a bright, indirect light until roots have formed, which can take up to four weeks. Once rooted, the cuttings can be transplanted into individual pots or directly into the ground.
Overall, propagation of Sphaeralcea rusbyi Gray ssp. gilensis Kearney is relatively easy, and both seed and vegetative methods can be successful with proper care and attention.
