It can tolerate a wide range of soils, including sandy and rocky soils, but prefers well-drained soils. It is also found in disturbed areas such as roadsides, fences, and abandoned fields.
Common Names and Uses
The common names for Oxalis albicans Kunth ssp. pilosa are pink woodsorrel and mountain oxalis. The plant is often grown as an ornamental due to its attractive pink flowers and its ability to spread quickly and form a dense groundcover. It is low-maintenance and can thrive in a wide range of soil and light conditions. Some people also use the leaves and stems of the plant in salads or as a garnish, as they have a tart and lemony flavor.
In addition, some Native American tribes have used the plant for its medicinal properties. For example, the Navajo people have used the plant to treat sore throats, stomachaches, and menstrual cramps. It contains oxalic acid, which can help to break down kidney stones and prevent their formation.
Light Requirements
Oxalis albicans Kunth ssp. pilosa (Nutt.) Eiten require bright, indirect sunlight for optimal growth. Too much direct sunlight can scorch the leaves, whereas insufficient light can lead to weak stems and poor flowering.
Temperature Requirements
The ideal temperature range for the growth of Oxalis albicans Kunth ssp. pilosa (Nutt.) Eiten is between 65-75°F (18-24°C) during the day and 55-65°F (13-18°C) at night. Temperatures above 85°F (29°C) can cause the plant to die back, whereas temperatures below 50°F (10°C) can cause the foliage to yellow and drop off.
Soil Requirements
Oxalis albicans Kunth ssp. pilosa (Nutt.) Eiten prefer well-drained, slightly acidic soil with a pH between 6.0-6.5. The soil should be rich in organic matter and have good water retention properties, without becoming waterlogged. It's best to avoid heavy soils that may hold too much water and not allow for proper drainage.
Watering Requirements
It's important to keep the soil moist but not waterlogged. Overwatering can lead to root rot, resulting in the death of the plant. Watering once a week, or when the top inch of soil is dry to the touch, is sufficient for Oxalis albicans Kunth ssp. pilosa (Nutt.) Eiten.
Fertilizer Requirements
Apply a balanced, water-soluble fertilizer once a month during the growing season. Avoid fertilizing during the dormant period as this can lead to excessive growth and weak stems.
Cultivation
The optimal conditions for growing Oxalis albicans Kunth ssp. pilosa (Nutt.) Eiten include well-draining soil, partial shade, and temperatures between 60 and 70 degrees Fahrenheit. It is recommended to plant the bulbs about six inches apart from each other and a depth of approximately two inches.
Watering Needs
These plants prefer moist soil but can withstand some dryness. It is essential to avoid overwatering, which may lead to root rot. In the summer months, ensure the soil is kept moist to aid in growth.
Fertilization
It is advisable to fertilize the soil with a balanced fertilizer, such as 10-10-10, during the plant's growing season. Apply the fertilizer at a rate of one tablespoon per four square feet.
Pruning
Oxalis albicans Kunth ssp. pilosa (Nutt.) Eiten are not heavy feeders, making pruning an unnecessary activity. However, it is advisable to deadhead the flowers to encourage continuous blooming. You can pinch off the spent blooms or use clean pruning shears to trim them off.
Propagation of Oxalis albicans Kunth ssp. pilosa (Nutt.) Eiten
Oxalis albicans Kunth ssp. pilosa (Nutt.) Eiten, commonly called Pink wood-sorrel, is a beautiful plant with delicate pink flowers that add a pop of color to gardens. Propagation of this decorative plant is easy and can be done using the following methods:
1. Seed propagation
The most common method of propagating Oxalis albicans is through seeds. The seeds of this plant can be found in the capsules that develop after flowering. Collect the mature capsules, dry them, and break them apart to obtain the seeds. Sow the seeds in a well-draining soil mix and cover them lightly with soil. Keep the soil moist and warm, and the seeds will germinate in about two weeks.
2. Division
Dividing the plant is another simple way to propagate Oxalis albicans. Dig up the plant and separate the clumps into smaller and larger sections. Replant the larger bits in the original spot, and the smaller clumps can be potted up as individual plants. The ideal time for division is in early spring or fall.
3. Stem cuttings
Stem cuttings can be used to propagate Oxalis albicans. Take the cuttings in the growing season when the plant has fresh and healthy shoots. Cut a stem that is about four inches long, remove the leaves from its lower half, and dip the stem in a rooting hormone. Plant the stem in a well-draining soil mix, keeping it moist and in indirect sunlight. The new plant will develop roots in about three to four weeks.
Overall, Pink wood-sorrel is an easy plant to propagate using seeds, division, and stem cuttings. With a little patience and care, you can enjoy this charming plant in your garden for years to come.
