Pistacia atlantica, commonly known as Mt. Atlas Mastic Tree, is a semi-deciduous tree that originates from the Mediterranean woodlands, maquis shrublands, and rocky hillsides of the Middle East and North Africa. It can achieve a height of 25-40 feet and a width of 20-40 feet. The tree has a rounded to spreading canopy with pinnate leaves that turn an attractive yellow to red in the fall. Its small, inconspicuous greenish-white flowers bloom in clusters, followed by red to blue-black berries that are attractive to birds.

The Mt. Atlas Mastic Tree is valued for its hardiness and adaptability to a range of conditions, making it suitable for xeriscaping and as a windbreak in arid and semi-arid regions. It is also used for reforestation and erosion control due to its robust root system. In cultivation, it thrives in full sun or part shade and can tolerate low to medium water conditions, preferring well-drained soils. While it is drought-tolerant once established, it benefits from occasional deep watering during prolonged dry periods. Gardeners should be aware that Pistacia atlantica can be susceptible to root rot if overwatered or planted in poorly drained soils. Additionally, it is potentially invasive in some regions, so it is crucial to consult local guidelines before planting.CC BY-SA 4.0
