General Appearance
Ilex cassine L. var. myrtifolia (Walt.) Sarg. is an evergreen shrub or small tree that grows up to 30 feet tall. The plant has a dense, pyramidal shape that may become irregular with age. The leaves are glossy, dark green, and have an oval shape with a smooth edge. The bark is light brown and smooth when young, but it becomes rough and scaly with age.

The plant produces small white berries that mature in the fall and persist throughout winter, providing food for birds and other wildlife.
Light Requirements
Ilex cassine L. var. myrtifolia (Walt.) Sarg. thrives in full sun or partial shade, making it a versatile plant for different locations. However, it grows best in filtered sunlight with some shade to protect it from the harsh afternoon sun.
Temperature Requirements
The plant can tolerate a wide range of temperatures, from cool to tropical climates. It is most common in the Southeastern United States but can also grow in northern states. Ilex cassine L. var. myrtifolia (Walt.) Sarg. can handle temperatures as low as 10 degrees Fahrenheit and as high as 100 degrees Fahrenheit, making it a hardy species.
Soil Requirements
The plant prefers moist to wet soils that are well-draining and slightly acidic. It can tolerate a wide range of soil textures from loamy to sandy soils. However, the species does not do well in clay or waterlogged soils. It is recommended to add organic matter or compost to improve soil structure and fertility.
Cultivation Methods
Ilex cassine L. var. myrtifolia (Walt.) Sarg., commonly known as dahoon holly or myrtle dahoon, is a small slow-growing evergreen shrub that can grow up to 20 feet tall. It is native to the southeastern United States and prefers to grow in well-drained moist soils in partial shade to full sun.
The plant is tolerant of various soil types, including sands, clays, and loams. It is also somewhat tolerant of salt spray and can grow in slightly salty soils. The best time to plant this shrub is in the spring when soil temperatures begin to warm up.
Watering Needs
While dahoon holly requires moist soils, it is essential to avoid overwatering the plant, which can lead to root rot. The shrub should be watered deeply once or twice a week during the growing season and less frequently in the winter months, when the plant is in a dormant state. The soil should be allowed to dry slightly between watering.
Fertilization
Dahoon holly doesn't require much fertilization. Applying a balanced slow-release fertilizer once in the spring can help promote healthy growth. Avoid over-fertilizing, as this can lead to excessive growth and reduced hardiness. Additionally, the shrub is tolerant of low soil nutrient levels, so fertilizing every other year might be sufficient for the plant.
Pruning
Pruning of dahoon holly should be done in late winter or early spring before new growth begins. The plant can be pruned to maintain a desired shape, remove dead or damaged branches, and encourage healthy growth. It's essential to use sharp, clean tools when pruning to minimize damage to the shrub. Additionally, since dahoon holly grows slowly, pruning should be done sparingly, so as not to stunt its growth.
Propagation of Ilex cassine L. var. myrtifolia (Walt.) Sarg
Ilex cassine L. var. myrtifolia (Walt.) Sarg., commonly known as dahoon holly, is a native plant of the southeastern United States. It is a popular choice for landscape use due to its beautiful foliage and attractive red berries. If you want to propagate dahoon holly, there are a few methods you can choose from.
Seed propagation
One of the most common methods of propagating dahoon holly is through seed propagation. To do this, you'll need to collect fresh seeds from the plant in the fall. You should sow the seeds immediately, as they have a short shelf life. Sow the seeds in a well-draining soil mix, and cover lightly with soil. Keep the soil moist and warm, and germination should occur within a few weeks.
Cuttings
Dahoon holly can also be propagated from cuttings. The best time to take cuttings is in late spring or early summer. Choose healthy, non-flowering shoots, and take cuttings that are 4-6 inches long. Remove the leaves from the bottom two-thirds of the cutting, and dip the end in rooting hormone. Plant the cutting in a well-draining soil mix, and keep it moist and warm. Roots should develop in 4-6 weeks.
Division
You can also propagate dahoon holly through division. This is best done in the early spring, before new growth begins. Dig up a mature plant and separate it into smaller sections. Each section should have a healthy root system and several stems. Replant each section in a well-draining soil mix, and keep the soil moist until new growth appears.
With proper care and attention, dahoon holly can be easily propagated using any of these methods. Consider which one works best for your needs and abilities, and enjoy the beauty of this Southern native plant.

Fungicides may also be effective in controlling powdery mildew.
Common Pests
Dahoon Holly is also susceptible to a variety of insect pests, including scales, aphids, and spider mites. These pests can cause damage by sucking the sap from the leaves and stems of the plant, which can cause wilting, yellowing, and leaf drop. To manage insect pests, it is important to monitor the plant regularly and to remove any affected leaves or branches as soon as possible. In severe cases, insecticides may be necessary to control infestations.
In addition to insect pests, Dahoon Holly is also susceptible to damage from deer and rabbits, which may eat the leaves and bark of the plant. To manage damage from these animals, it is important to protect the plant with physical barriers or repellents, such as fences, netting, or sprays.
