PLANTS AND ACCESSORIES
Rocks, twigs, bits of decaying wood, and other naturally indigenous materials are suitable for gardens in glass. Tufa rock is always good, whether the plants sink their roots into it or not. If you happen to live near an old ironworks, you’ll find fascinating pieces of slag in many sizes and colors.
But many of the figurines offered for sale in stores—bridges, benches, and the like—are questionable, even doubtful, in a setting with native plants. If they are to fit at all, they must be artistic, believable, and in exquisite harmony with everything else in the woodland scene. If you want to try it, set them in place, look at them from all angles, and think it over carefully. Decide whether they “belong” or are merely cute. Cuteness is something that lasts for a moment—beauty is something that is forever.
Just as with dish gardens, model landscapes, and other gardens where plants live and grow together, terrarium plants should be chosen first for their cultural compatibility. In fact, the principle is even more vital here because terrarium gardens are usually meant to be lasting. Think for a moment—you wouldn’t tuck a dry-growing peperomia in the soil beside a moisture-loving fern, or a cool-growing wild flower beside a tropical selaginella. They just aren’t meant to live with each other.
Next, size up your plants as to height—larger and bolder plants for the background or for accent, creepers for blending. In between should come the many flowering and foliage plants that make your garden a thing of beauty.
Many of these plants can be bought at florists’ shops or variety stores. Others are available by mail, including the wildlings. The woods are always a source, but conservationists urge all of us not to destroy plants carelessly or move them out of their native haunts to unfavorable locations.
I find that the plants available from mail-order specialists are reasonably priced and are always good sturdy stock. More on this in Chapter 13.
