@animo @InvaderXan @GwenfarsGarden @douginamug Evolution is mindless, until it creates minds. For example, animals can select one another as mates based on their apparent fitness. So instead of a pure survival-of-the-fittest, there is now a new element: a brain. It's survival of the fittest-and-most-outwardly-optimal. So in animals, learned strategies enter evolution such as deliberately punishing parasites.
Can plants influence their evolution in this way, by choosing mates or reactively penalising parasitism? Hard to know, but the assumption would be "no".
I would assume then, that evolution in plants is still a random process guided by an unthinking and brutal optimisation: death or life. But plants live long, their relationships with other plants can last their whole lives. And they are sexual, so they can evolve parallel traits at once. So I think evolution does slowly work for them towards cooperation and conflict resolution, also.
