what lasts long ....
I have had my two Helwingia japonica since 2017 - one ( male ) from a private source - the other ( female ) from a nursery in Holland ...so far I have never had seeds ...but this year it worked out and and I was able to collect numerous fruits day before yesterday
Picture see here :
Please look at pictures of Helwingia japonica on Google ...I can't find mine at the moment ....
Yesterday evening I cleaned the seeds ...it was quite a job ....
If you are interested please ask by PM
Sorry ...only swap possibly with plant friends from main land Europe ...with the Brexit it is not possibly send to UK
All the best
Hans
