Common names
Common names for Githopsis pulchella Vatke ssp. pulchella var. pulchella include Southwest bluecup, dainty bluecup, and Platte River bluecup.
Appearance
Githopsis pulchella Vatke ssp. pulchella var. pulchella is a small and delicate plant, usually growing up to 9 inches tall. This plant has blue-gray hairy stems, narrow leaves, and produces small blue flowers with white throats. The flowers bloom from late spring to early summer, and each flower lasts only for a single day.
Uses
Githopsis pulchella Vatke ssp. pulchella var. pulchella is primarily used for ornamental purposes due to its delicate and attractive appearance. It is often grown in rock gardens or used as a ground cover. This plant is not edible, and there are no known medicinal or culinary uses for it.
Light Requirements
Githopsis pulchella Vatke ssp. pulchella var. pulchella thrives in habitats that receive ample light. These habitats include exposed slopes, open woods, meadows, and grassy hills. When grown in a garden or greenhouse, the plant should be positioned where it can receive full sun or bright filtered light all day long.
Temperature Range
As a native of western North America, Githopsis pulchella Vatke ssp. pulchella var. pulchella is adapted to cool and temperate climates. It can tolerate a wide range of temperatures, with the optimum being between 50 and 77°F (10 and 25°C). The plant is not frost-tolerant and cannot survive prolonged exposure to temperatures below freezing point.
Soil Requirements
Githopsis pulchella Vatke ssp. pulchella var. pulchella is not particularly finicky about the soil it grows in. However, the soil should be well-drained, fertile, and slightly acidic. When grown in a container, a potting mix made of peat moss, vermiculite, and perlite can be used. In the wild, the plant is often found in soils derived from sandstone, shale, and basalt.
Cultivation
Githopsis pulchella is a sun-loving plant that does best in a well-draining soil that is slightly acidic. It can adapt to most soil types, but cannot handle standing water or soil that is overly compacted. The plant can grow in a rock garden, in a mixed border with other annuals and perennials, or as part of a wildflower meadow. It is hardy to USDA zones 5 to 9 and can handle temperatures down to -20°F (-29°C).
Watering Needs
Githopsis pulchella requires moderate watering during dry periods, with the frequency of watering dependent upon the amount of rainfall or irrigation the plant receives. Overwatering causes the plant's roots to rot and die, while underwatering quickens the plant's growth cycle, which leads to reduced foliage color and smaller blooms.
Fertilization
This species responds well to fertilization with bud-bloom food, flower-boosting fertilizer, or fertilizers with a high phosphorus content. Fertilizing the plant in early spring before the plant starts to flower is recommended, and additional fertilization in early summer can help to spur continued blooms throughout the season.
Pruning
Githopsis pulchella needs very little pruning. Deadheading, or the removal of spent flowers, encourages additional blooms and helps to keep the plant looking tidy throughout the growing season. The removal of damaged or diseased foliage or any dead wood is recommended for general plant health. Pruning should only take place after the last blooms of the season have died off.
Propagation of Githopsis pulchella Vatke ssp. pulchella var. pulchella
Githopsis pulchella Vatke ssp. pulchella var. pulchella can be propagated by seed or by vegetative means.
Propagation by seed
The seeds of Githopsis pulchella Vatke ssp. pulchella var. pulchella can be sown outdoors in the fall or indoors in the spring. The best time to sow the seeds outdoors is after the last frost date in your area. Before sowing the seeds, the soil must be prepared by removing weeds and debris and loosening the soil to a depth of about 6 inches. The seeds should be sown thinly and covered with a thin layer of soil. Water the soil and keep it moist until the seeds germinate, which usually takes about two to three weeks.
Propagation by vegetative means
Githopsis pulchella Vatke ssp. pulchella var. pulchella can also be propagated by vegetative means such as stem cuttings or division.
For stem cuttings, select a healthy stem from the parent plant and cut it just below a node. Remove the lower leaves and dip the cut end in rooting hormone. Plant the cutting in a well-draining potting mix and keep it moist until roots develop.
For division, carefully dig up the parent plant and separate the roots and stems into smaller sections. Replant the sections in a well-draining potting mix and water thoroughly.
Disease Management
The Githopsis pulchella Vatke ssp. pulchella var. pulchella plant is generally hardy and disease-resistant. However, they may experience some diseases caused by fungal infections such as root rot and powdery mildew.
To manage root rot, avoid overwatering the plant. Make sure the plant is well-drained, and the soil does not hold excess water. Remove any infected roots and dispose of them to prevent further contamination. If the infection persists, apply a fungicide according to the manufacturer's instructions.
Powdery mildew can be managed by removing any affected leaves and applying a fungicide according to the manufacturer's instructions. Avoid overhead watering, and maintain good air circulation to prevent the spread of the disease.
Pest Management
Githopsis pulchella is relatively pest-free, but some pests such as aphids, spider mites, and thrips may infest them. These pests may cause yellowing of leaves, stunted growth, and distortion of foliage.
To manage aphids, use a strong stream of water to wash them off the plant. Alternatively, apply insecticidal soap or neem oil to control the infestation. Repeat the treatment every few days until the infestation subsides.
To manage spider mites, spray the plant with a strong stream of water or apply insecticidal soap or neem oil. To prevent future infestations, maintain humidity levels by misting the plant frequently, and avoid overwatering.
To manage thrips, remove and dispose of any infested plant parts. Introduce natural predators like ladybugs or lacewings to control the infestation. Alternatively, apply insecticidal soap or neem oil to manage the infestation.
