The flowers are pink to purple in color and are arranged in a spiral pattern on the stem. The petals curve backward and resemble a shooting star, giving rise to the common name of the plant.
Uses of Dodecatheon salinum A. Nels.
Dodecatheon salinum A. Nels. is mainly grown as an ornamental plant, particularly in rock gardens or borders. It prefers well-drained soil with some moisture and can thrive in partial to full shade. It is not commonly used for medicinal or culinary purposes.
Light requirements
Dodecatheon salinum requires bright and indirect sunlight for optimal growth. In its natural habitat, the plant grows in sunny meadows and grasslands, but it also thrives in partially shaded areas. Excessive exposure to direct sunlight may cause the leaves to wilt and reduce plant growth.
Temperature requirements
The ideal temperature range for Dodecatheon salinum is between 15°C to 25°C (59°F to 77°F) during the day and between 5°C to 10°C (41°F to 50°F) at night. The plant can survive in colder temperatures, but prolonged exposure to freezing temperatures can cause serious damage to the plant.
Soil requirements
Dodecatheon salinum prefers well-drained soil that is rich in organic matter, such as loamy or sandy soils. The plant requires sufficient moisture, but it is crucial to avoid waterlogging as it can cause root rot. The pH level of the soil should range between 6.5 to 7.5, which is slightly acidic to neutral.
Cultivation Methods
Dodecatheon salinum A. Nels., commonly referred to as Saline Shooting Star, requires well-draining soil and lots of sunlight to thrive. It typically grows in meadows, wetlands, and along streamsides, thus prefers moist soil. This plant prefers acidic soils with pH 5-6; however, it can tolerate soils with a pH of up to 7.5. Plant them during the fall in small clumps. Ensure that the plants are placed 6-8 inches apart to prevent overcrowding.
Watering Needs
Saline Shooting Star requires consistent soil moisture, so watering is essential. Water newly planted dodecatheon salinum often, at least once a week, to promote rapid root growth. Once the plant is established and has developed a sufficient root system, you can reduce the watering to once a month. Avoid overwatering because this could lead to root rotting.
Fertilization
Saline Shooting Star is not very sensitive to fertilizers, so there’s no need to introduce synthetic fertilizers. Do not amend the soil with too much organic matter, which can lead to drying out of the soil. Instead, treat the plant every spring with a slow-release granular fertilizer to boost growth and encourage flowering.
Pruning
Dodecatheon salinum is a low-maintenance plant that rarely requires pruning. Deadhead when needed to promote the growth of new flowers. Once the plant has finished blooming, cut back the stems to keep the plant compact. This also promotes the efficient use of resources by the plant.
Propagation of Dodecatheon salinum A. Nels.
Dodecatheon salinum A. Nels., also known as the seaside Shooting Star, is a beautiful plant with flowers that range from magenta to lavender. Propagation of this plant can be done through several methods.
Seed Propagation
The most common way to propagate Dodecatheon salinum A. Nels. is through seeds. The ideal time to harvest the seeds is after the plant has bloomed and the capsules have turned brown. Sow the seeds in flats or pots filled with a well-drained potting mix in spring or fall. Cover them lightly with soil and keep the soil moist.
Division
Division is another way to propagate Dodecatheon salinum A. Nels. Divide the plant in spring before new growth begins. Carefully dig up the plant and separate the root ball into smaller pieces. Ensure that each piece has roots attached and replant them at the same depth as the original plant. Water well.
Cuttings
Propagation through cuttings takes more time and effort compared to other methods, but it is possible. Take stem cuttings in summer when the plant is actively growing. Remove all the leaves except for the top two and plant them in a well-drained potting mix. Keep the soil moist and in a shaded location. In a few weeks, a new plant will begin to grow.
Propagation of Dodecatheon salinum A. Nels. through all the methods mentioned above will give you the opportunity to grow more plants and expand their presence in your garden.
