Whatever happened to the house plant as major decorating feature? Only a couple of decades ago a living room wasn't complete without its own jungle or forty year old bonsai fig in the corner. Light weakly forced its way through a forest of african violets which had colonised kitchen window sills around the world and spider plants brooded sinisterly in macramé slings in every second bathroom. And those pom pom grandma flower arrangements? Are they now as dead as dodos? This week's retro revelation comes from Decorating with Plants and Flowers, Creative Home Library, Meredith Corporation, Des Moines, 1972. Perhaps we don't have to go to the extremes of years past but is there a little room in your house for our leafy friends?
