Pittosporum crassifolium. KARO. New Zealand
PITTOSPORACEAE (Pittosporum family)

A shrub or small tree with silvery gray appearance due to pale felted undersurfaces on the 2- to 4-inch leaves. Small deep magenta flowers occur in spring. Important New Zealand trees that grow in San Francisco and Santa Cruz are poorly represented at Stanford; for example kauri (Agathis australis), kowhai (Sophora tetraptera), and rimu (Dacridium cupressinum).

A trimmed hedge of Karo separates Branner Hall’s front garden from the parking lot to the west. A single specimen is on the path off Alvarado Row opposite San Francisco Court, near the drinking fountain.

Additions/Revisions: Look for Karo in other campus locations as a small tree, trimmed hedge, and a ground cover.
