Staghorn Sumac Rhus typhina Radiance = 'Sinrus'
ABOUT
The plant known as Staghorn sumac 'Radiance' is a striking deciduous shrub, notable for its distinctive foliage and vibrant seasonal color changes. The leaves are large, compound, and dissected into many smaller leaflets which are arranged in a feather-like pattern along the central stem. In spring and summer, the foliage is a fresh green hue, but as the seasons shift to autumn, the leaves undergo a dramatic transformation. They turn into a fiery display of oranges, reds, and yellows, lighting up the landscape with warm tones. In addition to the colorful foliage, Staghorn sumac 'Radiance' is recognized for its unique fruiting structures. The plant produces dense clusters of tiny, velvety berries, which stand upright above the foliage. These berry clusters are initially green, but they become a deep red as they mature, persisting through the winter and providing a striking contrast against the barren winter landscape. The reddish-pink berry clusters are not only visually appealing but also attract wildlife, offering a source of food for birds. The bark and stems of the Staghorn sumac 'Radiance' further contribute to the plant's ornamental charm. The young stems exhibit a fine, velvety texture, similar to that of a deer's antlers in the early stages of growth, from which part of its common name is derived. Over time, the bark becomes rough and deeply fissured, adding textural interest even in the dormant season when leaves are absent. This sumac's branching pattern is also noteworthy, as it tends to grow with a spreading, open habit. This gives the plant a somewhat architectural look, with branches reaching outwards and upwards in a manner that provides visual interest in the landscape year-round. The Staghorn sumac 'Radiance' is a robust and adaptable plant, well-suited for adding a touch of drama to gardens and naturalized areas with its alluring features and dynamic seasonal changes.

- Toxicity
To humans
Staghorn sumac is generally not considered toxic to humans; in fact, certain parts of the plant have been traditionally used in making beverages and spices. However, like other members of the Rhus genus, staghorn sumac can cause allergic reactions in sensitive individuals, similar to poison ivy, due to the presence of urushiol oil in the plant's sap. Contact with the sap can lead to dermatitis or a skin rash upon contact. Ingestion is not typically associated with serious toxicity, but it could potentially cause stomach irritation or discomfort in some people. It is advisable to handle staghorn sumac with care, especially if you have sensitive skin or known allergies to urushiol-containing plants.
To pets
Staghorn sumac is not known to be toxic to pets. Pets, like cats and dogs, might experience mild gastrointestinal upset if they consumed parts of the plant, mainly if they are not accustomed to it. However, as with humans, the main concern comes from the potential skin irritation that could result from contact with the plant's sap, which contains urushiol. While not poisonous, it is still best to discourage pets from chewing on or eating staghorn sumac to prevent any possible discomfort or allergic reactions.

- Water
Staghorn sumac should be watered deeply but infrequently, establishing a strong routine for the roots to grow deep and resist drought. For newly planted sumacs, water them twice a week with approximately 1-2 gallons depending on the size of the plant and weather conditions. Once established, they require less frequent watering, and you can reduce watering to once every two weeks if there is no significant rainfall, providing 1-2 gallons each time depending on the dryness of the soil.
- Light
Staghorn sumac thrives best in full sunlight, which means it should receive at least 6 hours of direct sun daily. The ideal spot for this plant would be an open area without shade from buildings or other trees to ensure it gets plenty of sunlight throughout the day. They can tolerate partial shade, but their fall color and overall growth might not be as vibrant.
- Temperature
Staghorn sumac is a hardy plant that can tolerate a wide range of temperatures, surviving winter lows down to around -30°F and summer highs exceeding 100°F. The ideal temperature conditions for this plant are between 60°F and 80°F, where it can grow vigorously and produce its distinct foliage and fruit.
- Pruning
Prune staghorn sumac to shape the plant, remove any dead or damaged wood, and encourage new growth. The best time for pruning is late winter or early spring before new growth begins. Pruning can be done every year, but is not strictly necessary unless the plant is becoming too large or unruly. Remember to make clean cuts and not to over-prune, as it could damage the plant's natural form.
- Cleaning
As needed
- Soil
Staghorn sumac 'Radiance' prefers well-draining soil with a pH range of 5.5 to 7.0. A mix of loam, coarse sand, and peat can create ideal conditions. Organic matter like compost can enhance soil fertility for optimal growth.

- Life cycle
The Staghorn sumac (Rhus typhina 'Radiance') begins its life cycle when the seeds germinate, typically in the spring following a period of cold stratification that breaks seed dormancy. After germination, the seedlings grow rapidly into young plants, developing compound leaves and a distinctive, hairy stem evocative of deer antlers in velvet. Given the right conditions, by the second or third year, the Staghorn sumac will mature and begin producing flowers; the male and female flowers are usually on separate plants. By late summer, female plants produce dense clusters of crimson drupes that persist into winter, providing food for wildlife. The plant also expands through its underground rhizome system, which causes the growth of new shoots around the parent plant and can lead to the formation of thickets. Over many years, this deciduous shrub can reach up to 25 feet in height, and it will continue to grow, reproduce, and spread until it reaches the end of its life span, which can be several decades under optimal conditions.
- Propogation
Propogation time
Spring-Early Summer
Propogation: The most popular method of propagating Staghorn Sumac 'Radiance' is through root cuttings. This involves excavating around the base of the mature plant to locate young, pencil-sized roots. The chosen roots are cut into sections approximately 3 to 6 inches (7.6 to 15.2 centimeters) long. These cuttings are then planted in moist, well-draining soil, ensuring that they are kept horizontal or with the end that was closest to the plant base in the upward position. It's ideal to take these cuttings during the plant's dormancy period, which corresponds to late winter or early spring. After planting, the cuttings should be watered regularly to maintain consistent soil moisture until they establish a new root system, after which they can produce new shoots and ultimately mature into separate Staghorn Sumac plants.
