Ethan Allen and Elvin McDonald

Back in 1977, Ethan Allen and Elvin McDonald of House Beautiful (ww.housebeautiful.com) gave a presentation called "Decorating with Plants."
McDonald revealed many new decorating-with-plant ideas.
Keep in mind; this was three decades before Instagram. Otherwise, McDonald would have no doubt share photos of the over 300 plants in his apartment.
In the newspaper promotions for his presentation, McDonald was quoted as saying,

"Take a pill if you will I say take a plant to cope with everyday stress."
