Report an issue with this species
Pittosporum crassifolium, also known as Karo or Seaside Pittosporum, is a fast-growing evergreen shrub or small tree native to New Zealand. It has an erect, fastigiate growth habit and is highly tolerant of coastal conditions, drought, smog, and saline soils. This makes it a durable and attractive choice for urban planting, attracting birds and maintaining clean, dense growth.
