Culture
Tolerates a wide range of soils, including poor, rocky, or sandy soils, as long as they are well-drained. Drought tolerant once established. Can be somewhat susceptible to wind damage due to its brittle wood. Prefers full sun for optimal growth and fruit production. Adaptable to various soil types, but good drainage is crucial. Avoid heavy, waterlogged soils.
Noteworthy Characteristics
Foliage is evergreen, feathery, pinnately compound leaves composed of numerous narrow, lance-shaped leaflets. The leaves have a distinctly resinous, peppery aroma when crushed. Flowers are small, inconspicuous yellowish-white to greenish-white flowers borne in pendulous panicles at the ends of branches. While not showy in themselves, they precede the attractive fruit. Fruit is abundant clusters of small, round, berry-like drupes that mature to a bright rosy-pink to red. These “pink peppercorns” are often used as a culinary spice, though they are botanically distinct from true black pepper (Piper nigrum). Bark is grayish-brown, becoming deeply furrowed and gnarled with age, adding an interesting textural element to the tree. Tree form is graceful, weeping form with airy, open branches, creating a distinctive silhouette.
Genus name is derived from the Greek word for Pistacia lentiscus, schinos, which it resembles.
Specific epithet is believed to origien from the word “mulli” which the Quechua Indians of Peru used for something soft.
Problems
Generally pest and disease resistant. Can be susceptible to scale insects and sooty mold in some climates. Its brittle wood makes it somewhat prone to limb breakage in high winds. Considered invasive in certain arid and semi-arid regions outside its native range (e.g., parts of California, Florida, Australia, and South Africa), where it can outcompete native vegetation. Its aggressive root system can also be problematic near structures, foundations, or plumbing. Users in appropriate regions should exercise caution and research local regulations regarding its planting.
Uses
Due to its graceful form, drought tolerance, and attractive fruit, it is often used as an ornamental tree in arid and Mediterranean climates. It can serve as a shade tree, specimen tree, or street tree in suitable locations where its invasive potential is not a concern or can be managed. The “pink peppercorns” are harvested and used in cuisine (though some individuals may have allergic reactions) and essential oil production.
