Last updated May 11, 2026

Pinus mugo (Pinaceae) is a variable, typically shrubby pine native to the mountains of central and southern Europe. It grows to about 8 feet tall in cultivation (taller in the wild), forming a dense, rounded to spreading mound. The stiff, dark green needles are held in pairs.

Mugo pine is one of the most widely used dwarf conifers, tolerating a wide range of conditions including cold, wind, poor soils, and moderate drought. It grows in full sun. The variety pumilio is more compact and prostrate. Many cultivars are available in sizes ranging from miniature rock garden forms to large shrubs. Hardy in Zones 2a to 8b.
