Those superbum seeds from Thailand have been tricky for me, but then again they weren't fresh like those you got.
Did the flowers bracts look purple like the ones Rare Palm Seeds is selling? Are they just selling the regular Thai superbum with a different name? I noticed that their(RPS) seeds were smaller that the other ones I got from Thailand as "rock banana", but that could be other factors too.

What do ya think?
