On acquiring fireberry seeds[edit source]
As far as I can tell it's impossible to get any seeds other than exuberry and rumberry in the wild. However, there's a berry planter on Tuai Leit, in which you can plant two seeds, of the same or different bushes. I planted exuberry on the west side and rumberry on the east (mentioning this in case orientation matters).
When I came back several hours later, both had grown, the rumberry bush was harvestable, and on harvesting it I instantly got 133 rumberries, 5 rumberry seeds, and one fireberry seed with the chat message of "The berry bushes have cross-pollinated and you find a new type of seed!". (I promptly planted the fireberry seed next to the barren exuberry bush.)
