Habitat : Rhus aromatica is native to Eastern N. America – Quebec to Florida and Indiana to Texas. It grows on dry rocks, sands and open woods, often on limestone outcrops.

Rhus aromatica is a low, irregular spreading shrub with lower branches that grow horizontally then turn up at the tips. Tends to sucker and root along stems that touch the soil, forming a dense stand. Yellow-green flowers appear before leaves emerge. Clusters of fuzzy red fruit form on female plants August-September and may persist into winter. Many birds and mammals feed on the fruit. Leaves turn bright red-purple in fall… & see the pictures

It is a woody plant that can grow to around 2 meters tall. It produces yellow flowers in clusters before anthesis. Hairy red drupes are produced, which can be brewed into a tea.


The leaves and stems of fragrant sumac have a citrus fragrance when crushed, and it inhabits mostly uplands areas, while poison ivy has no odor and can inhabit various habitats.

It is in flower in April, and the seeds ripen in September. The flowers are dioecious (individual flowers are either male or female, but only one sex is to be found on any one plant so both male and female plants must be grown if seed is required) and are pollinated by Bees.The plant is not self-fertile.

Succeeds in a well-drained fertile soil in full sun. Tolerates poor soils. Established plants are drought resistant. A very hardy plant when fully dormant, tolerating temperatures down to about -25°c. However, the young growth in spring can be damaged by late frosts. Many of the species in this genus are highly toxic and can also cause severe irritation to the skin of some people, whilst other species such as this one are not poisonous. It is relatively simple to distinguish which is which, the poisonous species have axillary panicles and smooth fruits whilst non-poisonous species have compound terminal panicles and fruits covered with acid crimson hairs. The toxic species are sometimes separated into their own genus, Toxicodendron, by some botanists. This species is a low suckering shrub. There is a specially low growing form, var. arenaria, that is found growing on sand dunes in the mid-west of N. America. A polymorphic species. Plants are susceptible to coral spot fungus. Plants have brittle branches that are easily damaged in very strong winds. Plants in this genus are notably resistant to honey fungus. This species transplants easily. The plant has an offensive smell. Or, to go by another nose, the bruised leaves emit a delicious resinous scent. Dioecious. Male and female plants must be grown if seed is required. Special Features:Attracts birds, North American native, Attractive flowers or blooms.

Seed – best sown in a cold frame as soon as it is ripe. Pre-soak the seed for 24 hours in hot water (starting at a temperature of 80 – 90c and allowing it to cool) prior to sowing in order to leach out any germination inhibitors. This soak water can be drunk and has a delicious lemon-flavour. The stored seed also needs hot water treatment and can be sown in early spring in a cold frame. When they are large enough to handle, prick the seedlings out into individual pots and grow them on in the greenhouse for their first winter. Plant them out into their permanent positions in late spring or early summer, after the last expected frosts. Cuttings of half-ripe wood, 10cm with a heel, July/August in a frame. Root cuttings 4cm long taken in December and potted up vertically in a greenhouse. Good percentage. Suckers in late autumn to winter

Edible Uses:
Fruit – raw or cooked. The fruit is small with very little flesh, but it is easily harvested and when soaked for 10 – 30 minutes in hot or cold water makes a very refreshing lemonade-like drink (without any fizz of course). The mixture should not be boiled since this will release tannic acids and make the drink astringent. The fruit can also be dried and ground into a powder then mixed with corn meal and used in cakes, porridges etc.

Medicinal Uses:
The root-bark  of   Rhus aromatica is astringent and diuretic. Used in diabetes and excessive discharge from kidneys and bladder. The wood exudes a peculiar odour and is used by the Indians in Arizona, California and New Mexico for making baskets.
