Growing African Blackwood tree from Seed?

I have purchased 50 Dalbergia melanoxylon, African Blackwood seeds.

I am in East Coast UK. Zone 8.

I tried to look for a care guide, but could not find much.

Did find a germination guide. It suggested that I sew seeds in a container at 25c in sand. It also suggest that I score (scratch) the seeds to allow them to sprout.

I can't find its zone hardiness, but did read about someone growing them and mentioning they were killed by a frost.

I plan to treat them like my citrus trees. Indoors in winter. Since they are so slow growing, I won't need to worry about them reaching over 2m for a while I guess.

I don't plan to bonzai them rather re-pot when required.

So just looking for tips on germination and after care. Also what is the germination rate like? I have grown several giant and coast redwoods from seed and they have a low germination rate. So just wondering how many seedling I will get from 50 seeds?

Thanks
