the Acacias I'm growing are:
Acacia Drummondii ssp drummondii (dwarf wattle)
Acacia Hunnardiana (prickly moses)
Acacia Pravissima (ovens valley wattle)
Acacia Cognata (cogs)
Here they are as seeds (mostly, I put the cog in the ground before I remembered I was supposed to take a pic of the seeds!
and here they are in the ground (with a box for fun)
the stacks are showing where the divided groups are.
