Mastic Tree
Pistacia lentiscus
shrubPistacia lentiscus, commonly known as mastic tree or lentisk, is a Mediterranean evergreen shrub prized for its aromatic resin and small red berries that turn black when mature. It has been cultivated for thousands of years, particularly on the Greek island of Chios, for the production of mastic gum. The plant features small pinnate leaflets with a distinctive aromatic fragrance when crushed.

Germination & Establishment
6-12 monthsSeedlings emerge slowly (4-8 weeks) with tiny compound leaflets. Young plants grow slowly and develop sparse branching.
Provide consistent moisture during first 6-12 months but never waterlog. Protect from frost if below zone 9. Light shade may help in very hot climates.
Vegetative Growth
1-2 yearsPlant develops woody stems and dense pinnate foliage with characteristic small leaflets. Slow but steady growth pattern; lateral branching increases.
Minimal fertilizer needed; nitrogen excess reduces hardiness. Prune lightly to shape in early spring. Drought stress after establishment is acceptable.
Maturation
2-3 yearsPlant reaches desired shrub size (8-15 feet tall and wide) with full canopy. Woody framework becomes dense and gnarled.
Minimal maintenance. Occasional pruning for shape. Provide full sun exposure for optimal resin quality.
Flowering & Fruiting
Continuous after year 3-5Small yellow-red flowers appear in spring (April-May). Female plants develop small spherical berries that transition from red to black in fall.
Both male and female plants needed for fruit set (dioecious). Resin exudation increases with plant age and stress. Harvest begins in late summer.
Resin Harvest & Production
Ongoing (decades)Mature trees (7+ years) produce commercially viable quantities of mastic resin. Small black berries persist on female plants through winter.
Traditional hand-harvesting of resin occurs August-September. Minimal additional care required. Trees improve with age.

Common Pests
-
Spray with horticultural oil in early spring; prune severely infested branches. Generally pest-resistant in Mediterranean climates.
-
Rare; manage with water spray or insecticidal soap if necessary. Drought-stressed plants more susceptible.
-
Prevent through excellent drainage; avoid overwatering. No chemical controls recommended; plant in well-draining soil.
Uses
Mastic Gum & Flavoring
CulinaryThe resin (mastic gum) is chewed as a breath freshener and used as a flavoring agent in Mediterranean cuisine, particularly in Greek and Turkish cooking. It imparts a slightly piney, resinous flavor to dishes, beverages, and desserts. [source]
Digestive & Anti-inflammatory Properties
MedicinalTraditional Mediterranean and Middle Eastern medicine uses mastic resin for treating digestive disorders, ulcers, and inflammation. Modern research suggests potential benefits for gastric health and antimicrobial properties. [source]
Varnish & Wood Finish
HouseholdHistorically used as a natural varnish, lacquer, and wood finish due to its protective resinous properties. Also used in traditional inks and adhesives. [source]
Incense & Perfumery
CraftMastic resin is burned as incense in religious and cultural ceremonies and used in traditional perfumery for its warm, aromatic fragrance. [source]
Food for Mediterranean Wildlife
WildlifeThe berries and foliage provide food and habitat for native Mediterranean birds, insects, and small mammals, supporting regional biodiversity. [source]

Harvest Tips
Mastic resin is traditionally harvested August-September by carefully cutting the bark and collecting the hardened resin that oozes out over 2-3 weeks. Resin appears as small amber-colored tears or nodules on the stem surface. Black berries can be collected in fall when fully mature (September-October) for culinary or medicinal use. Commercial harvesting typically begins on trees 7-10 years old and continues indefinitely with proper management.
Fun Facts
- 🌱 Pistacia lentiscus has been cultivated on the Greek island of Chios for over 2,300 years, with protected designation-of-origin status for 'Mastiha of Chios,' making it one of the world's oldest protected geographical indications for agricultural products.
- 🌱 The resin was historically used as a chewing gum by ancient Greeks and Romans, and modern mastic gum is still chewed as a breath freshener and digestive aid in Mediterranean cultures today.
- 🌱 The plant can live for several centuries and becomes increasingly productive with age; some ancient mastic trees on Chios are believed to be over 500 years old and still produce premium resin.
