However, this species prefers warmer temperatures ranging from 57°F to 82°F (14°C to 28°C) and will not tolerate frost. The plant can be grown in USDA hardiness zones 6 through 10, but it may not grow well in hot and humid summer climates.
Cultivation Methods
Gilia ophthalmoides Brand ssp. flavocincta (A. Nels.) A.& V. Grant is a plant that thrives best in well-draining soils that have adequate moisture retention capacity and at the same time allows for good aeration. They should be planted in an area that receives full sun to partial shade exposure. The plant does well in both acidic and alkaline soils with a pH range of 5.5-8.0.
Watering Needs
The plant is not very demanding when it comes to watering. It should be watered at least one inch per week, and extra care should be taken to ensure not to overwater the soil. Overwatering can lead to root diseases and cause the plant to rot. The plant should be watered deeply and less frequently to encourage the development of a robust root system.
Fertilization
It is recommended to fertilize Gilia ophthalmoides Brand ssp. flavocincta (A. Nels.) A.& V. Grant with a balanced fertilizer during the growing season. The fertilizer should be applied 4-6 inches away from the base of the plant in a circular pattern. It is advisable to use a slow-release fertilizer to prevent the leaching of nutrients from the soil.
Pruning
Gilia ophthalmoides Brand ssp. flavocincta (A. Nels.) A.& V. Grant is not a very demanding plant when it comes to pruning. However, pruning is necessary to remove dead stems and branches. The plant can be pruned in late fall or early spring. Dead or wilting stems and branches should be removed at the base of the plant with sharp pruning shears. Regular pruning encourages the plant to grow and produce more flowers.
Propagation of Gilia ophthalmoides Brand ssp. flavocincta (A. Nels.) A.& V. Grant
Gilia ophthalmoides Brand ssp. flavocincta (A. Nels.) A.& V. Grant can be propagated through different methods. The following are some effective methods for propagating this plant:
Seed Propagation
Seed propagation is the most common method for propagating Gilia ophthalmoides. The plant produces plenty of seeds that can be harvested after the blooming season. Harvest the seeds when they are dry and have turned brown. Then, remove the seeds from their pods and store them in a cool and dry place before planting them.
Plant the seeds in a well-draining soil mix. Keep the soil moist and warm, and provide the plants with plenty of light. The seeds should germinate within a few days. Once the seedlings have grown a few inches, they can be transplanted into their permanent location.
Cuttings Propagation
Gilia ophthalmoides can also be propagated through cuttings. The best time to take cuttings is during the spring or summer when the plant is actively growing. Select healthy stem cuttings with a few leaves from the parent plant.
Dip the cuttings into a rooting hormone and plant them in a well-draining soil mix. Keep the soil moist, but not too wet, and provide the plants with plenty of light. The cuttings should develop roots in a few weeks. Once the roots have developed, the plants can be transplanted into their permanent location.
Division Propagation
Division is another method for propagating Gilia ophthalmoides. This method is best used for mature plants that have overgrown their location or need rejuvenation. Division should be done during the plant's dormant season, which is usually in fall or early winter.
Dig up the root ball and use a sharp knife or garden shears to divide the plant into two or more sections. Ensure each section has healthy roots and some stems. Plant each new section into its permanent location, ensuring proper care such as watering and light requirements.
