"Most persons are interested in plants, even though they do not know it. They enjoy the green verdure, the brilliant flower, the graceful form. They are interested in plants in general. I wish that every person were interested in some plant in particular. There is a pleasure in the companionship, merely because the plant is a living and a growing thing. It expresses power, vitality. It is a complete, self-sufficient organism. It makes its way in the world. It is alive.
The companionship with a plant, as with a bird or an insect, means more than the feeling for the plant itself. It means that the person has interest in something real and genuine. It takes him out-of-doors. It invites him to the field. It is suggestive. It inculcates a habit of meditation and reflection. It enables one to discover himself." -L.H. Bailey, Planting a Plant, 'Nature-Study Quarterly, No. 8 : Leaflet 21, January, 1901
