Common Names
The plant has several common names, including Sandhill Rockcress, Sandhill Mustard, and Sandhill Tower Mustard.
Uses
Sandhill Rockcress is not widely used for medicinal or culinary purposes. However, it is sometimes used in restoration and conservation efforts to prevent soil erosion on sandhills and other sandy habitats.
General Appearance
The Sandhill Rockcress plant typically grows 1-3 feet tall and has lavender or white flowers that bloom from March to May. Its leaves are alternate, lanceolate, and lobed. The plant has a woody taproot and is well-suited to surviving in sandy soils, which many other plants cannot tolerate.
Light Requirements

Temperature Requirements
The plant can tolerate a wide range of temperatures, from -23°C to 30°C, making it quite adaptable to different climates. However, it is important to note that the plant may not survive in extremely hot and humid conditions, which may lead to heat stress and root rot.
Soil Requirements
The plant prefers well-drained soil that is moist but not waterlogged. A pH range of 6.0 to 7.5 is optimal for its growth, and it can tolerate a wide range of soil textures, from sandy to loamy. The soil should be rich in organic matter and fertilized regularly to promote healthy growth.
Cultivation methods for Arabis ovata sensu Small
Arabis ovata sensu Small, non Michx. is a hardy and easy-to-grow plant that can thrive in various soil types and light conditions. To cultivate it, start by selecting a site with well-draining soil and partial to full sun exposure. This plant can grow up to 18 inches tall and 24 inches wide, so make sure to space them apart at least 12 inches from each other.
Plant the seeds in early spring or fall, ? inch deep in the soil and four to six inches apart. Water the soil gently to keep it moist but not too wet, as Arabis ovata sensu Small prefers well-drained soil. Once the seedlings reach two to four inches tall, you can thin them out to one foot apart.
Watering needs for Arabis ovata sensu Small
Arabis ovata sensu Small requires moderate watering, particularly during its first year of growth. Water your plant deeply once a week during the growing season, especially during prolonged dry spells. Ensure that the soil dries out completely between watering to avoid waterlogging, which can lead to root rot and stunted growth.
Fertilization for Arabis ovata sensu Small
Arabis ovata sensu Small is not a heavy feeder and requires minimal fertilization. During the planting process, incorporate compost or well-rotted manure into the soil to provide nutrients for healthy growth. During the growing season, you can use a balanced fertilizer once every month to support the plant's growth. Apply the fertilizer around the plant's base, taking care not to get it on the leaves or stems as a concentrated solution can burn the plant.
Pruning Arabis ovata sensu Small
Arabis ovata sensu Small requires minimal pruning except to remove dead stems or leaves. After flowering, cut back the plant to encourage bushier growth and prevent self-seeding, which can lead to overcrowding. You can also shear the plant lightly to maintain its shape and prevent it from becoming leggy.
Propagation Methods of Arabis Ovata Sensu Small, Non Michx.
The plant Arabis ovata sensu Small, non Michx., commonly known as the Rockcress, belongs to the Brassicaceae family. The plant is native to the southeastern United States.
Propagating from Seeds
The most common method of propagating Arabis ovata is from seeds. The seeds can be collected from the plant after the pods ripen and turn brown. Once collected, the seeds should be dried and stored until planting time.
In order to propagate from seeds, sow them in a potting mix that drains well. Cover the seeds with a thin layer of soil, and water them regularly. Keep the pots in a warm, sunny location until germination occurs.
Once the seedlings have reached a height of four inches, they can be transplanted into a larger container or directly into the ground.
Propagating from Cuttings
Another method of propagating Arabis ovata is from cuttings. Cuttings should be taken from the plant during the spring or early summer months. Choose a stem that is healthy and free of disease and insects.
Once a stem has been selected, cut a three-inch section from the tip of the stem. Remove all the leaves from the cutting except for the top two or three leaves. Dip the cut end of the stem in rooting hormone and place it in a potting mix that drains well.
Keep the pot in a warm, sunny location and water the cutting regularly. Once the cutting has developed roots, it can be transplanted into a larger container or directly into the ground.
Disease and Pest Management for Arabis ovata sensu Small, non Michx
Arabis ovata sensu Small, non Michx is generally a healthy plant. However, it can be affected by several pests and diseases. Proper management practices are necessary to keep the plant healthy. Here are some of the common diseases and pests that might affect the plant and their management.
