I am very rude about the many Pittosporums growing here in the garden, speaking mainly about pruning and chopping them down. I need to set the record straight - Pittosporums are very beautiful foliage shrubs and trees.
Two Pittosporums by a Rustic Fence
Many things about Pittosporums make them the most useful shrub/trees. They will accept hard pruning without sulking - simply making fresh regrowth quickly. Thus a tree which has outlived its space in a border can be turned magically into a small leafy shrub.
Trees From Seedlings
Another good thing is that many types of Pittosporums provide seedlings, and as long as you transplant them early you can use them for filling in new gardens, forming screens, etc.
There are many types of hybrid Pittosporums, all having masses of beautiful leaves (big and small). They are evergreen, and many types have subtle variegations.
