Mike this is a pretty unusual weedy native for our area. It has only been sparingly planted in our region. The Atlas of Living Australia also has naturalised records from within the Botanic Gardens and at Queanbeyan. Would be interested if you ever observe fruit on a naturalised plant.

This has some buds on it but there is a 60% chance it is a male tree so there won't be fruit. There are a couple of trees about 4-5m tall at the corner of Julia Flynn Ave and Shepherson Place, Isaacs that don't have buds so maybe it is marginal climate for flowering.

The 40+ year old 1 m tall shrub of Pittosporum undulatum in my garden flowers profusely most years, but i have never noticed seedlings. It is quite frost tender when young. On the other hand, Pittosporum angustifolium has the occasional rampant seedling. I have just checked the family Pittosporaceae in Plantnet. The whole family has bisexual flowers.

I looked at the Quensland Government Weeds of Australia keyserver.lucidcentral.org which says 'separate male and female flowers are usually borne on different plants'. The 60% male I got from Gleadow, Ros; Walker, Jeff (May 2014) 'The Invasion of Pittosporum undulatum in the Dandenong Ranges. Victoria: realising predictions about rates and impact',Proceedings Fifth Victorian Weeds Conference. What would we do without Wikipedia?

Thanks Betty and Mike - probably a plant to keep our eyes on, but not get alarmed about.
