General Appearance
Rhus virens Lindheimer ex Gray var. choriophylla has shiny, dark green leaves that are serrated and lance-shaped. The plant has a dense, rounded canopy and branches that grow outward and upward. Its bark is gray and smooth and becomes rough with age. The flowers of this plant are small and white, while its fruits are small, red, and hairy.
Light Requirements
Rhus virens Lindheimer ex Gray var. choriophylla requires full sun exposure for optimal growth. The plant can tolerate partial shade but may not thrive or produce as many blooms as it would in full sun. Therefore, it is best to plant this species in areas that receive at least six hours of direct sunlight per day.
Temperature Requirements
This plant is native to Texas and thrives in warm, arid climates. The ideal temperature range for Rhus virens Lindheimer ex Gray var. choriophylla is between 70°F to 90°F (21°C to 32°C) during the day and 50°F to 70°F (10°C to 21°C) at night. It is essential to note that this plant is not frost-tolerant, and temperatures below 20°F (-6°C) can cause significant damage to the plant.
Soil Requirements
Rhus virens Lindheimer ex Gray var. choriophylla prefers well-draining soils that are slightly acidic to neutral. They can grow in sandy, loamy, or rocky soils and can tolerate drought conditions once established. However, organic-rich soil is ideal, and the addition of organic matter can improve soil nutrients, structure, and retain moisture. This plant can also grow in nutrient-poor soils, making it suitable for xeriscaping gardens.
Cultivation
Rhus virens Lindheimer ex Gray var. choriophylla (Woot. & Standl.) L. Benson, commonly known as Evergreen sumac, is a tough, drought-tolerant plant native to Texas and New Mexico in the United States. This plant prefers a well-drained, nutrient-rich soil, preferably slightly alkaline. Evergreen sumac can thrive in full sun or partial shade, making it a versatile addition to landscapes.
Propagation of Evergreen sumac can be achieved through seeds or cuttings. Cuttings should be taken from semi-hardwood stems and rooted in a well-draining soil mix. Once established, Evergreen sumac requires minimal care and can tolerate poor soil quality, making it an ideal plant for low-maintenance gardens.
Watering Needs
Evergreen sumac is a drought-tolerant plant that can survive extended periods without water once established. However, for optimal growth and health, the plant requires regular watering during its first year after planting. After that, watering can be done once or twice a month, depending on the climate and soil type.
The soil around Evergreen sumac should be allowed to dry out between watering to prevent root rot. It is better to water deeply and less frequently instead of frequent shallow watering. Mulching around the plant can help to retain moisture in the soil and prevent moisture loss through evaporation.
Fertilization
Evergreen sumac is a low-maintenance plant that doesn't require regular fertilization. However, to promote healthy growth and blooming, fertilizer can be applied once a year in the early spring. A balanced slow-release fertilizer can be used, following the manufacturer's instructions on the package.
It is essential to avoid over-fertilizing Evergreen sumac as it can lead to rapid growth, weak branches, and susceptibility to pest infestations.
Pruning
Evergreen sumac requires minimal pruning and can be left to grow naturally. However, it can become leggy and sparse if not properly maintained. To promote denser growth and a more attractive shape, prune the plant lightly, removing up to one-third of the growth every year in the late winter or early spring.
Dead or damaged branches can be removed at any time of the year, and suckers should be pruned to prevent the plant's spread. Always use clean, sharp pruning shears to avoid damaging the plant and spread disease.
Propagation methods for Rhus virens Lindheimer ex Gray var. choriophylla
Rhus virens Lindheimer ex Gray var. choriophylla, commonly known as Evergreen sumac, is a hardy shrub native to Texas and northern Mexico. Propagation of this plant can be achieved through a few methods:
1. Seed propagation
Rhus virens can be grown from seed. The seeds can be harvested from mature fruits in the fall or purchased from a reputable dealer. The seeds require a period of stratification to germinate, meaning they need to be exposed to cold temperatures for a certain period to break their dormancy. Once stratified, the seeds can be sown in early spring or late fall in a well-draining soil mix. Keep the soil moist and the seeds in a bright and warm location to encourage germination.
2. Semi-hardwood cuttings
Rhus virens can also be propagated through semi-hardwood cuttings. Cuttings should be taken in late summer to early fall and should be approximately four to six inches long. Remove the leaves from the bottom half of the cutting and dip the cut end into rooting hormone. Place the cutting into a well-draining soil mix or substrate and keep it moist and in a shaded location. Once the cutting has rooted, it can be transplanted into a larger container or planted outdoors.
3. Division
Rhus virens can be propagated through division. This method is best employed for mature plants that have outgrown their containers or are in need of renovation. To divide the plant, remove it from its container and use a sharp, sterile knife to cut the plant into sections that contain both roots and shoots. Re-pot the divided sections or plant them outdoors in well-draining soil in a bright and sunny location.
Propagation of Rhus virens Lindheimer ex Gray var. choriophylla is relatively easy using any of the above methods. With a little patience and the right conditions, you can create a beautiful addition to your garden or landscape.
