A plantsman (plantswoman) is one who loves plants for their own sake and knows how to cherish them. This… concept… may include a botanist: it certainly includes a host of admirable amateurs who may not know what a chromosome looks like or what taxonomy means, but they know the growing plant, wild or cultivated, first-hand. To my mind they are the cream of those in the plant world, a fund of invaluable first-hand information."
