Temperature Requirements
Saxifraga eschscholtzii Sternb. is native to the Pacific Northwest region of North America, where it can experience a wide range of temperatures. It can withstand temperatures as low as -10°C (14°F) during the winter months. During the summer, it can tolerate temperatures up to around 30°C (86°F). However, it generally prefers cool to moderate temperatures and can thrive in areas where the temperature ranges between 10-25°C (50-77°F).
Soil Requirements
Saxifraga eschscholtzii Sternb. prefers well-draining soils that are rich in organic matter. It can grow in a range of soil types, including sandy loam, loam, silt loam, and gravelly soils. However, it does not do well in heavy clay soils. The ideal pH range for growing Saxifraga eschscholtzii Sternb. is between 6.0-7.5. To improve drainage, it is beneficial to mix in some sand or peat moss into the soil before planting.
Cultivation
Saxifraga eschscholtzii Sternb. is a hardy perennial plant that can grow in a variety of soil types. It prefers well-drained soil with a pH range of 5.5 to 7.5. This plant thrives in areas with full to partial sunlight. It can also tolerate cold temperatures and even grows in alpine and subalpine regions.
Watering Needs
This plant needs regular watering, especially during the growing season. Water the Saxifraga eschscholtzii Sternb. once or twice a week, keeping the soil moist but not waterlogged. During the winter months, water it less frequently, only when the soil becomes dry. Avoid using hard water as it can affect the soil's pH and reduce the plant's growth.
Fertilization
While Saxifraga eschscholtzii Sternb. does not need excessive fertilization, you can add a balanced fertilizer once a month during the growing period to improve its growth. Use a slow release fertilizer that provides all the essential nutrients required for the plant. Over-fertilizing can damage the plant and cause stunted growth.
Pruning

Propagation of Saxifraga eschscholtzii Sternb.
Saxifraga eschscholtzii Sternb. can be propagated through various methods, such as seeds, division, and stem cuttings. Each method has its advantages and disadvantages, and it is essential to choose the method suitable for the plant to ensure successful propagation.
Propagation by Seeds
Propagation by seeds is the most common method of propagating Saxifraga eschscholtzii Sternb. It is a simple method, and the seeds can be harvested from mature plants. The seeds need adequate moisture and warmth to germinate, and they can take up to several months to germinate. Once the seedlings are mature enough, they can be transplanted to their final position.
Propagation by Division
Propagation by division involves separating the parent plant into smaller sections with roots and foliage. This method is ideal for mature plants, and it helps promote new growth. Division is best done in the spring or fall, and the separated sections should be planted at the same depth as the parent plant, and in a well-draining soil.
Propagation by Stem Cuttings
Saxifraga eschscholtzii Sternb. can also be propagated by stem cuttings, but this method is more challenging than the other methods. The cuttings should be taken from the parent plant in the spring, and they should be about 3-4 inches long. The cuttings should be treated with rooting hormone and planted in a well-draining soil. The soil should be kept moist, and the cuttings should be placed in a sheltered area until they root and produce new foliage.
Overall, Saxifraga eschscholtzii Sternb. can be propagated through various methods, and each method has its advantages and disadvantages. Propagation by seeds is the easiest and most common method, while propagation by division and stem cuttings can be more challenging but can also promote new growth.
