Arbutus unedo ‘Mercurius’ (PBR) is a slow growing strawberry tree selected for its dense growth and reliable flowering and fruiting. Glossy evergreen leaves provide structure throughout the year, while in autumn clusters of small, urn-shaped white flowers appear alongside ripening red, textured fruits from the previous season, creating a distinctive two-stage display. Chosen for its tidy habit and strong garden performance, ‘Mercurius’ is well suited to smaller gardens, borders, and sheltered planting schemes. It thrives in a sunny position with well-drained soil and tolerates coastal conditions once established, offering consistent year-round interest with minimal maintenance.
