Hi mindperformer,
many thanks for your reply
In the meantime I ordered some of the seeds of this seller, I attached a picture of the seeds I got.
I hoped that I at least would get a Toromiro Hybrid or anything like this.
The seeds I got don´t look that dark like in the picture I posted above.
I think it could be Sophora cassioides as well, since the seeds seem to have some similarities to Sophora cassiodes seeds.
Many thanks for the link to Kowhai germination, it could prove useful in the future
