To help with identification use the key from here. Seed Germination in Pittosporum. Seed can be gathered from the capsules in autumn. In all cases capture the seed as soon as they open. It is necessary to clean the sticky tar away from the seed. Mix the sticky seeds with sand and shake in a plastic bag. Removal of the tar makes it easier foreven distribution on the seed raising mix. Many people chose to stratify the seeds. This is placing the cleaned seed in the refrigerator for about a month. The idea is that cold storage provides a winter environment for the seed, so when they are removed from the refigeratorthe seeds sense a change of temperature, and believing it to be spring, the seed germinates. Evidence suggests that startification may not improve over all germination, rather, it produces more uniform germination. Sowing seed without stratifcation results in germination ofthe seeds over a longer period of time which may be 2 or 3 years. They sometimes show three or four cotyledons (seed leaves) instead of the usual two.
