The trees are purely affected by the asteroid attributes,, not by the seedlings used to plant them :-)
Is there a difference to the tree what the size/attributes of the asteroid that the flower comes from? That is, does the flower bring any stats from it's origin asteroid to the tree? I've been wondering about that for some time.
Yes, I think the flower take all stats from it's origin asteroid, so that some flower is big, some small, and the speed is different. but when the flower be planted, that stats increase to the tree, is not as more as image.
