Growth Conditions for Lithophragma tenellum Nutt. var. thompsonii (Hoover) C.L. Hitchc.
Lithophragma tenellum Nutt. var. thompsonii (Hoover) C.L. Hitchc., commonly known as Thompson's prairie star, is a herbaceous perennial plant that is native to the western United States. This plant species is typically found in grassy meadows, rocky slopes, and forests with well-drained soils and partial shade.
Light Requirements
Thompson's prairie star performs best in partial shade to full sun conditions. When grown in full sun, this plant may require more frequent watering and soil moisture management to prevent drought stress.
Temperature Requirements
Thompson's prairie star thrives in temperate climates and is adapted to grow in USDA hardiness zones 5-9. The optimal temperature range for this plant is between 65-75°F during the day and 50-60°F at night. Sudden temperature changes and frost can cause damage to the plant.
Soil Requirements
The soil for Thompson's prairie star should be well-drained, rich in organic matter, and preferably slightly acidic with a pH of 6.0-7.0. This species prefers soils with good moisture retention and does not tolerate drought or waterlogged soils. In addition, the plant benefits from a layer of mulch to retain soil moisture and regulate temperature.
Cultivation Methods
Lithophragma tenellum Nutt. var. thompsonii (Hoover) C.L. Hitchc. is a hardy perennial that is native to North America. It belongs to the saxifrage family and is commonly known as Thompson's or Mountain saxifrage. When it comes to cultivation, the plant prefers to grow in well-draining soil and areas with partial shade to full sun exposure. It can be grown either in garden beds or containers and can be propagated easily either by seed or division.
Watering Needs
Mountain saxifrage prefers to grow in well-drained soil, but it also requires adequate moisture to thrive. The optimal way to keep the plant hydrated is by watering it deeply and infrequently, rather than frequently with shallow waterings. Check the soil regularly, and water only when the soil is almost dry. Mountain saxifrage is drought-tolerant, so be careful not to overwater the plant.
Fertilization
Lithophragma tenellum Nutt. var. thompsonii (Hoover) C.L. Hitchc. is a light feeder, which means that it does not require much fertilizer to grow. You can apply a balanced, slow-release fertilizer once a year in spring to give the plant a boost. However, it is important to avoid over-fertilization, as it can cause the plant to produce more foliage than flowers.
Pruning
Maintaining the plant's shape is essential to keep it healthy. Prune the plant after blooming to encourage it to produce more flowers the following year. Deadheading spent flowers also helps the plant conserve energy for the next blooming season. Cut the flower stems down to the base of the plant with clean, sharp shears. Use clean pruning tools to avoid transmitting any diseases to the plant.
Propagation Methods
Lithophragma tenellum Nutt. var. thompsonii (Hoover) C.L. Hitchc. can be propagated through seeds, division, and stem cuttings. The preferred propagation method depends on the overall growth habit and the purpose of the plant.
Propagation by Seeds
Propagation by seed is the easiest and most common method for Lithophragma tenellum Nutt. var. thompsonii (Hoover) C.L. Hitchc. The seeds should be collected once the seed pods have turned brown and split open. The seeds should be sown immediately in a well-draining medium, such as a 1:1 ratio of sand and potting soil.
The seeds should be lightly covered with soil and kept moist until germination. Germination typically occurs within 1-2 weeks. Once the seedlings have produced their second set of true leaves, they can be transplanted into individual pots or directly into the garden bed.
Propagation by Division
Propagation by division is another effective method for Lithophragma tenellum Nutt. var. thompsonii (Hoover) C.L. Hitchc. This method is particularly useful for mature plants that have outgrown their space or are in need of rejuvenation.
To propagate through division, the plant should be carefully dug up and gently separated into smaller clumps with a sharp knife. Each clump should have its own set of roots and foliage. The newly divided plants should be immediately replanted into their new location and kept moist until established.
Propagation by Stem Cuttings
Propagation by stem cuttings is a more challenging and less common method for Lithophragma tenellum Nutt. var. thompsonii (Hoover) C.L. Hitchc. This method is best suited for individuals with experience propagating plants from cuttings.
To propagate through stem cuttings, select healthy stems that are 4-6 inches in length and remove the lower leaves. Dip the cutting in rooting hormone and plant it in a well-draining medium, such as a 1:1 ratio of sand and potting soil. Keep the soil moist and provide bright, indirect light. The cutting should root within 4-6 weeks and can be transplanted once it has established a root system.
Disease and Pest Management for Lithophragma Tenellum Nutt. Var. Thompsonii (Hoover) C.L. Hitchc.
