Light Requirements

Temperature Requirements
The plant is native to California and prefers a dry Mediterranean climate. It can thrive in a wide range of temperatures from 32°F to 105°F. However, it is not frost-resistant and dies back during winter dormancy when exposed to frost or freezing temperatures. Therefore, it is best grown in areas that do not experience severe winter frost.
Soil Requirements
Camissonia integrifolia Raven prefers well-draining, sandy, and slightly acidic soil. It can adapt to various soil types, including loam, clay, and sandy soils, as long as the soil is not waterlogged. The plant is well-suited to grow in nutrient-poor soils and thrives in dry soil conditions. It is not recommended to plant the plant in heavy or waterlogged soils, which can lead to root rot and other fungal diseases.
Cultivation Methods for Camissonia integrifolia Raven
Camissonia integrifolia Raven is a hardy plant that is easy to cultivate. It thrives in areas with full sun exposure, well-drained soil that is nutrient-rich. This plant is well suited for USDA hardiness zones 9 and 10, but it can be grown in other areas as well.
The recommended time to start planting Camissonia integrifolia Raven is early summer. The seeds should be sown directly into the soil after preparing the soil-bed by loosening up the soil and adding compost. Place the seeds about 1/4 inch deep into the soil, and then cover them with a light layer of soil. The soil should be kept moist for the first few weeks but avoid over-watering as it can lead to damping-off disease.
Watering Needs
Camissonia integrifolia Raven is a drought-tolerant plant once it has established itself. It is essential to water the newly planted seeds until they germinate. The plant should be watered infrequently but deeply, allowing the soil to dry out partially before the next watering. During the hot and dry seasons, the plant may require more watering to keep the soil from completely drying out.
Fertilization
Camissonia integrifolia Raven needs very little fertilization. However, if the soil is deficient in nutrients, adding organic fertilizers such as compost or well-rotted manure once a year can help promote healthy growth. It is recommended to apply the fertilizer after the plant has gone dormant at the end of its flowering cycle.
Pruning
Camissonia integrifolia Raven does not require much pruning. However, it is advisable to trim the plant lightly after it finishes flowering to promote more growth. This plant has a tendency to self-seed, so if you want to avoid having too many plants, cut the stems back before the seeds can disperse.
Propagation of Camissonia integrifolia Raven

- Sow the seeds on the surface of the soil and cover lightly with soil mix.
- Water gently and place the container in a warm and sunny spot.
- Keep the soil moist and germination should occur within two weeks.
Propagation by Stem Cuttings
Propagation by stem cuttings is another viable option for propagating Camissonia integrifolia Raven. The ideal time to take cuttings is in the spring or summer when the plant is actively growing. Follow these steps to propagate Camissonia integrifolia Raven from stem cuttings:
- Take a stem cutting from a mature plant that is at least 6 inches long.
- Cut the stem just below a leaf node.
- Remove the lower leaves from the cutting.
- Dip the cut end of the stem in rooting hormone powder.
- Plant the cutting in a well-draining soil mix with a high perlite content and vermiculite.
- Keep the soil moist and place the container in a warm, bright, and humid spot.
- Rooting should occur in about three to four weeks.
