Pittosporum tree
Pittosporum craqssifolium

This New Zealand Pittosporum is known for its toleration of seaside conditions and its versatility for growing as a hedge or small tree. Gray green foliage on 1-2 inch oval leaves. Trunk is gray and mottled like our coastal oak. Vivid maroon flowers are striking in this framework and are sweetly fragrant. Spring flowers are followed by tri part pods that split open to reveal black seeds. Seeds have a historic use as a blue dye down under and can stain sidewalks.

Karo can be grown as a hedge — there are lower growing varieties like 'Compactum' that are well suited for this purpose. Taller varieties can be shaped as a small street tree with yearly pruning to achieve this effect.
