Artificial lighting is a help even for the casual grower—one who has only a few plants, whether by happenstance, for the fun of it, or simply because “a house is not a home” without a plant or two. Table, desk, and floor lamps can be used to supplement the natural light from windows. Too often windows are shielded by trees or the house next door, or perhaps it is winter and there isn’t enough light to keep most plants in a thriving condition. Just turning on a lamp so that the rays fall on a plant can lengthen the hours of light enough to bring out bloom that might otherwise be impossible.
Tropical plants with controlled light, heat, and moisture make a “jungle garden”
Miniature plants and gardens are, of course, shining prospects for growth under artificial light. They take so little space, and since there is a limit to the height, width, and depth a single installation will illuminate, you can make the most use of it if you are growing the little fellows.
Here’s how the “jungle garden” came to be our source of continual refreshment and pleasure. Our living and dining rooms, both rather small, are separated partially by deep shelves. The previous owners of the place, devout music-lovers, used the shelves for their hi-fi set and stacks of phonograph records. Our record player—pardon me, our stereophonic hi-fidelity music box—has its own cabinet, and that left a gap in the divider between the two rooms. We naturally thought of plants, particularly the tender tropical miniatures I collect. Since we still hope to do extensive remodeling, the garden was not built permanently into the shelves, but was constructed as a separate case.
We are fortunate in having a generous friend who loves to work with fine wood, and can make cabinets with the precision of the real professional. The case he turned out is a beauty. It measures eighteen inches by twenty-four inches inside. The top rests on strong metal rods at the corners. Window glass slides horizontally in the grooves cut in the top and bottom, enabling us to open or close the case as need be. The inside of the top is painted white, thus reflecting the light from the lamps downward on the plants. We use both fluorescent and incandescent lights which are mounted on the underside of the top. The bottom of the cabinet is lined with the heaviest plastic we could find.
At first the case was used as an indoor greenhouse for many potted plants that need protective warmth and humidity. Several inches of vermiculite in the plastic lining were kept moist constantly, with the sides being opened or closed for ventilation.
Later, we filled the bottom with rich potting soil and put the plants’ roots right in it—climbers, creepers, tiny bush-shapes and trees. This turned out to be more of a “jungle” than we expected. Some notably delicate residents seeded themselves and started families. A dainty cissus strung itself langorously from one end to the other. The creeping fig nearly strangled the frail, whiskery bertolonia. But the planting was a source of delightful surprises—a bud here, a flower there, increasing colonies of some delicacies we hadn’t been able to grow at all, before.
Several years ago a bookcase which I set up in my office as a garden was the object of considerable attention—how much I never realized until I dismantled it and gave away the plants. Then, I was bombarded with questions—and even some complaints that I had taken away this spot of greenery. From the night watchman up to the president of the company, people missed those plants. Some even thought I must have been fired.
There is a little house in Levittown, one which I always enjoyed visiting. The second floor has two finished rooms, one of which then was the office-den of the hard-working Elvin McDonald of Flower and Garden. (He has since moved to Kansas City.) His tiered plant table with fluorescent lights was there for a functional reason, but it had a decorative value as well. In other homes I’ve seen plants growing by hundreds under lights in unused bedrooms, single specimens displayed in shadow boxes with circular fluorescent tubes, decorative gardens thriving in all sorts of dark corners. With artificial lighting taking care of the space problem, just about anyone can grow plants.
