SOLVED. Plants are taking over the earth; growing quickly and seeming to be intelligent. I think the setting is the Pacific Northwest [s]

It seems the author used initials for the first/middle name. It is an adult science fiction book bout an environment that is changing from "human run" to "plant run". I recall that the main character goes to live in the wild...

The Day of the Triffids ??

Ops sorry the first/middle name initials doesn't apply here.

That sounds like the beginning of The Family Tree by Sheri S. Tepper, although the environment is just as much "animal run" as "plant run."
