Plants as therapy

1976, hardcover edition, Praeger, NY. 194 pages. Elvin McDonald, a Garden Editor, wrote tons of books, including this one, where he came right out and said what everybody else was thinking. Stress could be relieved by house plants. That there was, in fact, green for the blues. And, yes, plants could be your friends. While the rest of the world is spinning by you, colleges began offering degrees in horticultural therapy, as well as other institutions of learning that provided the therapy, with no degree. Just when you think you've read and heard everything, here's this different, fascinating title.
