Origin and Distribution
The few-flowered shooting star is native to western North America, where it can be found growing in moist meadows, along streams and in open woods, from British Columbia south to California and east to Montana and Wyoming.
Common Names
The few-flowered shooting star is commonly known as the few-flowered shooting star, few-flowered dodecatheon, and few-flowered wild-primrose.
Appearance
The few-flowered shooting star grows up to 30 cm in height and has a basal rosette of lance-shaped leaves. The flowers, which appear in late spring to early summer, are 1-2 cm in length, and have five petals that are deep pink, magenta or purple in coloration, with a yellow throat. The flowers are borne on a tall, slender stem rising above the foliage. The fruit is a capsule.
Uses
The few-flowered shooting star is often used in wildflower gardens, and their showy flowers make it a popular choice for ornamental planting. Native communities have also traditionally used it as a medicinal plant for a variety of ailments.
Light Requirements
Dodecatheon pulchellum spp. pauciflorum prefers partial to full shade. It can tolerate some sunlight in the morning or late afternoon, but full sun exposure may lead to heat stress, scorch, and sunburn. In shaded areas, the plant typically develops larger leaves and more flowers, while in open areas, it tends to have smaller leaves and fewer blooms.
Temperature Requirements
The plant is native to cool temperate regions, so it prefers cool and moist conditions. It can tolerate occasional frosts and snow, but prolonged exposure to freezing temperatures may damage the foliage and roots. The optimal temperature range for growth is between 10 and 20 °C (50-68°F). In hotter regions, the plant may go dormant to conserve moisture and energy.
Soil Requirements
Dodecatheon pulchellum spp. pauciflorum grows well in well-draining, acidic to neutral soils that have high organic matter content. The soil should be moist but not waterlogged, and it should retain some level of moisture throughout the growing season. The plant can thrive in various soil types, including sandy, loamy, and clay soils.
Cultivation Methods for Dodecatheon Pulchellum ssp. Pauciflorum
Dodecatheon pulchellum ssp. pauciflorum, also known as few-flowered shooting star, is a hardy perennial plant that is native to North America. It typically grows in moist meadows and woodlands. This plant prefers well-draining soil with a neutral to slightly acidic pH level and partial to full sun exposure.
You can propagate shooting stars through seeds, division, or cutting. When planting, make sure to dig a hole big enough to accommodate the roots and loosen the soil around it. Cover it with soil, but do not bury it too deeply. Mulching around the base of the plant will also help to retain moisture and suppress weeds.
Watering Needs for Dodecatheon Pulchellum ssp. Pauciflorum
Shooting stars need regular watering to thrive but are susceptible to root rot in soils that are too wet. Keep the soil moist but not wet, especially during drought periods. It would help if you watered frequently during dry spells, and make sure the soil drains well. Avoid splashing water onto the foliage when watering, as this can cause leaf spotting and diseases.
Fertilization for Dodecatheon Pulchellum ssp. Pauciflorum
Shooting stars prefer nutrient-rich soils. You can add organic matter, such as compost or well-rotted manure, to the soil before planting to provide the plant with nutrients. Fertilize the plant lightly during the growing season with a balanced fertilizer to promote healthy growth. Avoid fertilizing once the flowering has started.
Pruning for Dodecatheon Pulchellum ssp. Pauciflorum
Pruning is not necessary for shooting stars. However, removing spent flowers will encourage the plant to produce more flowers. Deadheading will also prevent the plant from self-seeding if you do not want it to spread. In late fall, tidy up the plant by cutting back the foliage to the ground. This will help to prevent the buildup of debris around the plant that can cause diseases.
Propagation of Dodecatheon pulchellum ssp. pauciflorum
Dodecatheon pulchellum ssp. pauciflorum is commonly known as the dark-throat shooting star. It is a small, clump-forming perennial that is native to North America. The plant is notable for its showy flowers with pink or lavender petals and a dark purple throat.
Propagation methods
Dodecatheon pulchellum ssp. pauciflorum can propagate through both seeds and cuttings.
Propagation through seeds
The seeds of Dodecatheon pulchellum ssp. pauciflorum can be sown directly into the soil or started indoors and transplanted later. Sow the seeds in moist soil with good drainage, and keep them evenly moist until they germinate. The ideal temperature for germination is between 60°F and 68°F. The seeds should germinate within two to four weeks.
Propagation through cuttings
Dodecatheon pulchellum ssp. pauciflorum can also be propagated through stem cuttings. Cut a stem from the plant that is at least four inches long and has several leaves. Remove the lower leaves and dip the cut end in rooting hormone. Plant the cutting in a pot with a soilless mix, and keep it in a warm, humid location. Keep the soil moist but not too wet, and avoid direct sunlight. The cutting should develop roots within four to six weeks.
Overall, Dodecatheon pulchellum ssp. pauciflorum is a relatively easy plant to propagate, and both seed and cutting propagation methods can be successful with proper care.
