Growing Rhus Aromatica

Rhus is a plant genus comprising about 250 species of flowering plants that are native to North America. One species that is particularly popular among gardeners and landscapers is Rhus aromatica. This perennial shrub is commonly known as fragrant sumac, due to its pleasant scent. It grows 1.5 to 2 feet in height and spreads 6 to 8 feet. Its foliage consists of glossy green leaves that feature three leaflets. The yellow flowers give way to clusters of red berries. It works well as an ornamental plant.

There are several things to consider when planting and growing fragrant sumac. The condition of the soil, the climate, and certain pests or diseases can affect the health of Rhus aromatica.

Climate

This shrub thrives in hardiness zones 3 to 9. It prefers full sunlight, rather than partial shade.

Soil Conditions

The fragrant sumac grows well in several types of soil including sandy, loamy, and rocky soil. The main requirement is that the soil is well-draining. Poorly draining soil will lead to root rot, which is a condition that deteriorates the structure and function of the plant’s root system. It does well in soil with a neutral pH.

Watering and Fertilizers

This plant doesn’t need that much water. It tolerates dry soil. Avoid over-watering this plant. This is a fast-growing shrub that doesn’t need additional liquid fertilizer.

Propagation

The best way to propagate this plant is by sowing seeds. Another option is to take semi-hardwood cuttings and plant them.

Pests and Diseases

Some insects which may feed on this plant include scales and aphids. Aphids are particularly worrisome since they attract the sooty mold fungus. The fragrant sumac is susceptible to leaf spot and rust, both of which are fungal infections.
