Portugal Laurel

Prunus lusitanica

Rosaceae · broadleaf evergreen shrub · introduced

Last updated

Prunus lusitanica (Rosaceae) is a broadleaf evergreen shrub or small tree native to Spain, Portugal, and the Azores. It grows to 15 to 20 feet tall with a dense, rounded habit. The dark green, glossy leaves are smaller and more refined than those of P. laurocerasus. Slender racemes of fragrant white flowers appear in late spring, followed by small dark fruit.

Portuguese laurel is hardier than bay laurel and more refined in texture than cherry laurel. It grows in full sun to part shade on well-drained soil. The species makes an excellent formal hedge, topiary subject, or small standard tree. It is slower growing than P. laurocerasus and generally less susceptible to shothole disease. Hardy in Zones 7a to 8b.
