Common Names
The plant goes by several common names, including Payson's draba and Payson's whitlow-grass.
Uses
Draba paysonii J.F. Macbr. var. paysonii is not widely used for medicinal or culinary purposes. However, it is a preferred food source for livestock and wildlife such as cattle, sheep, and deer, especially during the winter season when other food sources become scarce.
General Appearance
Draba paysonii J.F. Macbr. var. paysonii is a small, herbaceous perennial plant that grows up to 7.5 cm in height. It has basal rosettes of leaves that are 2-3 cm long and 1-2 mm wide. The stems are slender and bear clusters of small flowers that are typically white or pale yellow in color. The plant blooms from May to July. The fruit is a linear silique, 1-2 cm long, and 1.5-2 mm wide.
Light Requirements
Draba paysonii J.F. Macbr. var. paysonii prefers full sun to partial shade for optimal growth. In low light conditions, the plant may struggle to produce enough energy for metabolic processes, leading to stunted growth and reduced vitality.
Temperature Requirements
The plant is adapted to grow in cold, alpine environments, and prefers cool temperatures. The ideal temperature range for growth is between 45-75°F (7-24°C), with the plant thriving in cooler temperatures at higher elevations. At lower temperatures, the growth may slow down, and the plant may enter dormancy during the winter months.
Soil Requirements
Draba paysonii J.F. Macbr. var. paysonii prefers well-draining, sandy or rocky soils with a pH between 5.5-7.5. The plant is adapted to grow in harsh, nutrient-poor soils typical of alpine environments. Soil that is too wet or heavy can lead to root rot, which can harm the plant's growth.
Cultivation Methods
Draba paysonii J.F. Macbr. var. paysonii, also known as Payson's draba, is a perennial plant that grows well in rocky or gravelly soils in open, sunny areas. The plant requires well-drained soil with a neutral to slightly alkaline pH level. It's essential to ensure adequate drainage to avoid waterlogging, which can cause root rot. If cultivated in a pot, pick one that has a bigger size than the root ball of the plant to offer enough space for growth.
Watering Needs
The plant requires regular watering, but it's crucial to avoid overwatering. Ensure to water the plant thoroughly, allowing the water to soak through the soil but making sure not to let the plant sit in standing water. During the hot summer months, Payson's draba may need more water than usual. Check the soil moisture to determine if the plant requires watering. However, reduce watering during the winter months or when the plant is dormant.
Fertilization
Payson's draba doesn't require much fertilizer and can survive without it, but occasional feeding can benefit the plant. Fertilize the plant with a general-purpose fertilizer, following the manufacturer's instructions. Apply the fertilizer during the growing season, ensuring not to over-fertilize, which can cause salt damage to the plant.
Pruning
Payson's draba does not require regular pruning. However, it's essential to remove any dead or damaged foliage or stems as soon as possible to prevent the spread of bacteria or pests that can harm the plant. A slight trim to shape the plant can be done after flowering. When pruning, use sharp and clean pruning shears to make a clean cut without damaging the healthy tissue.
Propagation of Draba paysonii var. paysonii
Draba paysonii var. paysonii, commonly known as Payson's draba, is a small, perennial plant native to the western United States. The plant is known for its attractive yellow flowers and fine-textured foliage.
Propagation by Seed
The most common method of propagating Draba paysonii var. paysonii is by seed. The seeds of the plant are small and should be sown in a well-draining soil mix in early spring. The soil should be kept moist but not wet, and the seeds should be covered lightly with soil.
Germination usually occurs within 2-3 weeks, and the young seedlings can be transplanted to individual pots when they have developed their first true leaves. The plants can be planted outdoors when they are well-established and the soil has warmed up in late spring or early summer.
Propagation by Cuttings
Draba paysonii var. paysonii can also be propagated by cuttings taken in late spring or early summer. The cuttings should be taken from the tips of the plant, and the leaves on the lower half of the stem should be removed.
The cuttings should be dipped in rooting hormone and planted in a well-draining soil mix. The soil should be kept moist, and the cuttings should be covered with a plastic bag to maintain humidity until they have rooted. The new plants can be transplanted outdoors once they are well-established.
Propagation by Division
It is also possible to propagate Draba paysonii var. paysonii by division. This method is best done in early spring before the plant has started to grow actively. The plant should be lifted from the soil carefully, and the clump should be divided into several smaller sections, each containing some roots and foliage.
The new plants can be replanted in well-draining soil and kept moist until they are well-established. This method can be used to rejuvenate older plants or to increase the number of plants in the garden.
