Safety Overview
1.Sumac — Introduction & Highlights
Sumac, or Rhus coriaria, is a resilient deciduous shrub in the Anacardiaceae family. This group also includes well-known species such as mango and poison ivy. The plant typically reaches 1 to 4 meters tall and has a robust structure. Its compound leaves are quite substantial. They measure between 10 and 30 cm long and contain 11 to 31 distinct, serrated leaflets. Each leaflet is about 3 to 10 cm long and 1 to 5 cm wide.
A delicately toothed margin gives the foliage its distinctive look. During the warmer months of June through August, Sumac produces dense, upright clusters of greenish-yellow flowers known as panicles. These panicles can extend up to 15 cm long and are a magnet for various pollinators. The bark of younger Sumac plants is smooth and grayish-brown. It gradually becomes rougher and more textured with maturity. Rhus coriaria is remarkably adaptable and thrives in a range of environments.
It strongly prefers dry, rocky soils, but it can also colonize disturbed areas. This adaptability explains its widespread distribution across the Mediterranean basin and into southwestern Asia. The plant is most recognized for its vibrant red, tangy fruits, which ripen in late summer. People traditionally harvest, dry, and grind these berries into a popular spice known for its unique lemony flavor. The berries are central to the plant's long-standing culinary and medicinal heritage.
