Pittosporum
Pittosporum umbellatum

The name Pittosporum is translated as Pitch seed which refers to the sticky seeds. Capsules 3 or 4 valved. An interesting feature is that some Pittosporums have 3 or 4 cotyledons, not the usual two. Seeds are slow to germinate, and most require a period of stratification. They should be scraped in sand to remove the sticky tar from the seed, then washed in warm running water. Store in the fridge for 60 days.The most success I have had with this genus is when I removed seed, ripe from the previous autumn, from the tree in spring. The seed had naturally gone through stratification over winter on the tree and it germinated readily once sown in October.
Pittosporum have become a very popular ornamental shrub or tree.
