Trish,

In the book Growing Australian Native Plants from seed by Murray Ralph it
says:-
"Seed germinates easily if sown fresh. For B.celisissima remove the seed
from the green fruits before sowing. Lightly cover seed. Seed loses
viability over 3-5 years".

If you are sowing them fresh maybe try and get the seeds from another
source.

Hope this has helped

David

... has anyone had any success at propagating _Buckinghamia celsissima_
from seed?

I've had a few goes at it, but have never even got as far as
germination! I was wondering whether the seeds might need to be
scarified or soaked or smoked or burnt (sorry for the bad timing!)?

Any suggestions most gratefully received! :-)
