Nearly any plant can grow in a vertical garden depending on the conditions. The following is a list of plants that we have used and had success in vertical gardens.
The Just Right Environment
As all green thumbs know; Plants can only thrive in their optimal environment. Most vegetables and Herbs require full-sun and hot summers to thrive. Succulents like to be dry and in full to part sun. Ferns like shady bright light areas that are moist and cool at night.
Our indoor environment is best for 'House Plants'. Most of which are native to the shady floors of tropical rain-forests. Ideally, this is also the same 70 degree environment where humans thrive. So it's only natural that we would want to fill our lives with plants.
Outdoors there are so many choices and so many options. Indoors has more limitations due to the low light and low humidity for most locations.
Overall the Philodendron family is the most tough. There are many colors of foliage and bold stems and roots. They can drape down or reach upward. And most can be transplanted from cuttings which means you can literally spread your garden around.
Low Light Tropical Plants
For walls across from windows or there is only artificial light available. Halogen floods provide the best artificial light but are big users of power, consider high intensity LED spots or fluorescent flood lights. Use a light meter to insure a minimum 250 foot candles falls on all the plants. The more you can provide the more healthy the plants will be.
Bright Light Tropical Plants
Indirect natural light can provide ample illumination for Indoor locations across from a bank of southern windows or a skylight. 700 foot candles will keep these plants happy. Or an array of metal halide floods can provide adequate illumination.

Nothing is more delightful than a wall of cascading ferns. They love bright indirect light 700 foot candles but typically prefer shade to part shade conditions. They are home to the Pacific Northwest where they are constantly in moisture and they prefer cool evenings with slight breezes. Many ferns will also do great mixed in with a bright light tropical collection.
