Overview:
Eremalche parryi (Greene) Greene ssp. kernensis (C.B. Wolf) Bates is a flowering plant belonging to the family Malvaceae. It is native to California in the United States, specifically in the Mojave and Sonoran deserts.
Common Names:
The plant is commonly known as Kern mallow, Parry's mallow, or apricot mallow.
General Appearance:
Eremalche parryi can grow up to 1.5 meters in height and 0.75 meters in width. The plant has slightly hairy stems and leaves that can reach a length of up to 10 cm. The bright orange or apricot-colored flowers can bloom from February to June, with petals up to 5 cm in length. The flowers produce round fruits that contain 10-20 seeds.
Uses:
The Native American tribes, including the Cahuilla and Kumeyaay, used the plant for various purposes. They used the leaves to create poultices that were applied to wounds or used to treat sore throats. The roots were used to make a decoction that was taken to treat coughs and chest pains. Additionally, the plant attracts pollinators, including bees and butterflies, making it a useful addition to gardens and landscapes.
Light Requirements
Eremalche parryi ssp. kernensis, commonly known as Kern mallow, requires full sun exposure to thrive. It is tolerant of the hot and dry conditions typical of its native habitats and can withstand direct sunlight for most of the day.
Temperature Requirements
This plant prefers warm and moderate temperatures. It is well-adapted to the California climate, where temperatures can range from 65 to 85 degrees Fahrenheit. However, it can tolerate occasional fluctuations in temperature and even withstand light frost.
Soil Requirements
Kern mallow is a drought-tolerant plant that prefers well-draining soils. It is naturally found in sandy soils but can also grow in clay and loam soils with good drainage. The ideal soil pH for this plant falls between 6.5 to 7.5. It is important to note that too much water can be harmful to this plant, so it is necessary to let the soil dry out completely before watering again.
Cultivation methods
Eremalche parryi (Greene) Greene ssp. kernensis (C.B. Wolf) Bates, commonly known as Kern mallow, is a hardy plant that can grow in various types of soil, including sandy, loamy, and clayey soil. For best results, plant in well-draining soil under full sun to partial shade conditions.
Watering needs
Kern mallow requires moderate watering, especially during its initial growth stage. Water the plant regularly but be cautious not to overwater as it may lead to root rot. The frequency of watering can be reduced once the plant has established itself.
Fertilization
It is recommended to fertilize Kern mallow during its growing season, usually in the spring and summer months, with a balanced fertilizer. Apply a slow-release fertilizer to the soil, which will provide nutrients gradually over time without overwhelming the plant.
Pruning
Kern mallow requires minimal pruning, primarily to promote the growth of a strong and healthy structure. Remove any dead, damaged, or diseased branches regularly to prevent insect infestations and ensure healthy growth. Pruning can also help shape the plant and reduce its size, but be careful not to over-prune as it can harm the plant.
Propagation of Eremalche parryi (Greene) Greene ssp. kernensis (C.B. Wolf) Bates
Eremalche parryi (Greene) Greene ssp. kernensis (C.B. Wolf) Bates, commonly known as Kern mallow, is a shrub native to California. It is a drought-tolerant plant that can grow up to 4 feet in height and spread up to 3 feet wide.
The propagation of Kern mallow can be done by either seed or stem cuttings. The ideal time for propagation is during the spring when new growth emerges.
Seed Propagation
To propagate Kern mallow from seed, gather mature seeds from the parent plant during the fall. The seeds should be dried and stored in an airtight container until spring. In spring, plant the seeds in a well-draining soil mix in a pot or directly into the ground. The soil should be kept moist until germination, which can take up to four weeks. Once the seedlings sprout, gradually reduce watering to prevent root rot.
Stem Cutting Propagation
To propagate Kern mallow from stem cuttings, take a healthy stem cutting in the spring, 4-6 inches in length, that does not have any flowers or buds. Dip the cut end in rooting hormone and plant it in a well-draining soil mix. Keep the soil moist and provide shade for the first few days to prevent wilt. The roots should appear in 3-4 weeks, and once they develop, the cutting may be transplanted into a larger pot or directly into the ground.
Propagation is a cost-effective way to obtain new plants and increase plant populations. With the right care and attention, Kern mallow can be propagated successfully by both seed and stem cuttings, allowing you to enjoy this beautiful shrub for years to come.
Disease Management
Eremalche parryi (Greene) Greene ssp. kernensis (C.B. Wolf) Bates is not prone to many diseases and is generally a hardy plant. However, it can be susceptible to root rot if the soil is consistently moist or if drainage is poor. To prevent root rot, make sure the soil is well-drained and avoid overwatering the plant. Additionally, if your plant starts to show signs of root rot, it may be best to remove it to prevent the spread of the disease to other plants in the area.
Pest Management
Eremalche parryi (Greene) Greene ssp. kernensis (C.B. Wolf) Bates is also quite resistant to pests but can occasionally be home to spider mites or aphids. Spider mites can be identified by the presence of a fine webbing and yellowish discoloration on the leaves. Aphids, on the other hand, are small, pear-shaped insects that tend to cluster together on new growth. These pests can be removed by spraying the plant with a strong jet of water, which will knock them off the plant. Alternatively, you can use neem oil, insecticidal soap or horticultural oils to control their population.
