Yavanna's Chosen

[Raynor]

'Yes, I do know [Gandalf]: the only wizard that really cares about trees,' said Treebeard.

Well, we might attribute that to many things. On one hand, Gandalf may have impressed the ent very much, with his dedication, passion, and possible higher spiritual standing, so that even if the other istari did they best, they just couldn't measure up to him. On the other hand, how extensive would this ent's knowledge of the deeds of the istari be? He doesn't strike me as a being that would wander high and low, get into contacts/talk with other races, or keep a watch over others, so as to measure them. To a certain degree, the influence of Gandalf on the affairs of the incarnate has been quite subtle, why couldn't we say the same about the deeds on Aiwendil in regards to nature?
