All and every Spirit Plant is a treasure of heaven and earth whether they are useful or useless
Of course, even if all of them are treasures of heaven and earth it doesn't mean that they are all equal just like how mages differ in strength
A quality 1 vismian grass is a treasure of heaven and earth but they are not particularly valuable and there are literally millions of them in the world
The Blue Jade Tree on the other hand is a rare almost impossible to possess Spirit Plant
Even a seed of this tree is incredibly precious. Not to mention, even if a person got a hold of the seed, they would still need to pay a heavy price for the seed to germinate, grow into a tree, and bear Blue Jade Fruits
Whether it be the clans of mages or formidable organizations in this world, all of them want to have a Blue Jade Tree
The top forces of the world have this kind of tree as one of their foundations
