Bromeliads: Tillandsia Air Plants
If you want to learn basic information about the bromeliad plant genus Tillandsia, this writing and photos will get you started. Plants of the genus Tillandsia are being raised by bromeliad lovers over the world. Hundreds of species are available from nurseries around the world and they are exhibited prominently in botanical gardens everywhere and in terrariums all over the world. This writing does not cover using tillandsias (air plants) in terrariums or other displays which will be undertaken in a future article.
For many gardeners starting a collection of tillandsias becomes an obsession. Read on to begin your obsession.
What is a Tillandsia?
The bromeliad genus Tillandsia is a popular genus of plants raised by discriminating plant lovers everywhere. In nature Tillandsia species can be found in southern United States through Central America and practically all of South America. As a group they are often called air plants since many of them can get their water from rain and their nutrients from rain and airborne dust and decaying organic matter. They are easy to grow as most of them require lower levels of light and can stand periods of drought. Many of them can be mounted on a board or on a limb in a tree or grown in osmunda. They reproduce by producing pups as is common in the bromeliad family.
The genus Tillandsia was established in 1753 by Linnaeus, the famous scientist that started the system of classifying plants that we use today. It is the largest bromeliad family and it has a very wide range of size, form and color variation. This plant family also shows the widest range of plant adaptation: from terrestrials (growing in soil) to atmospherics (air plants that do not use roots for water and nutrient uptake).
The diversity of tillandsias is almost open ended. So, recognizing the various plant genera is difficult and is regularly consigned to research specialists called taxonomists. Be sure when you acquire a new bromeliad that you get the name of it and use that name any time you mention the plant. Bromeliads do not generally have common names (a few cultivars [mating of two different species] do), so we have to learn the same name that scientists use. (Of course, sometimes we give our very favorite plants special names on our own.) Each of the photos in this writing have the scientific name in the form that is always used.
The following table might help you better understand the diversity found in the tillandsia family of plants, but you will have to see many of them before you will be able to recognize them. Once you do, you will wonder why everybody can't do it.
Always entire: never with spines or toothed edges
Often covered with trichomes (white scales)
Upright or pendant w/ single flower to cone or blade
Covered with bracts (modified leaves)
Usually tubular with open petals
Predominately white, blue, yellow
Tillandsia is the largest genus in the family, with 650 known species and more to be named. They are typically gray-leafed plants native to bright, semiarid habitats; most are absent the rosette so they do not hold water. Culturing them is fairly easy as the need little care. Instead of symmetrical rosettes of leaves, some tillandsias have twisted, undulating, or curled leaves. Others have succulent leaves, or form hollow bulbous structures at the bases of the plants. Still others develop long, almost vine like stems. Much of the appeal of this genus is due to these strange growth forms.

The genus Tillandsia has an undeserved reputation for being difficult to grow from seed. In fact, tillandsias are among the easiest plants in the world to grow. Most species also have a reputation for being very slow. Some are, but under generous cultural conditions many of the popular species can be grown to maturity in five years or less.
It is not always possible to tell if tillandsia seed is viable. In many species the seed begins to germinate before the capsule splits, indicated by a little green nubbin at the end of the coma (the feathery tuft of hairs that carry the seed on the wind). In other species the seed looks brown and lifeless. It may still be good, so sow it. Sow tillandsia seed as soon as possible after the capsule breaks open; however, it remains viable for a few weeks under normal environmental conditions and longer under refrigeration.
Once the plants get to the seedling stage they can be planted where you want them and the following table will help you in taking care of them. However, each species will have an optimal environment. Often your environment is not this optimal place for them to grow best. Use the information in the table to start and then start placing them in different places until you find the best place for them to grow in what you can produce.

Books on Amazon
There are several books on tillandsias, but the really reliable ones are quite expensive and many of the others are not particularly well written. However, there is a new book by Zenaida Sengo that might fit the bill for our purposes. It is slanted toward presentation rather than the biology of tillandsias, but that is partially the beauty of tillandsias, they are marvelous no matter how or where you grow them. And, reading this book with the many different photos will inspire toward presenting them in unusually beautiful ways.
"Sometime around 50 to 60 million years ago, an obscure group of primitive plants that probably resided in what is today northern South America began to evolve to become what botanists recognize as family Bromeliaceae. Many of the bromeliads--along with members of some 75 other families, including the orchids--acquired the means to root on bark rather than in the ground. Growing epiphytically presents special challenges, for which the bromeliads have evolved quite unique solutions. This book not only profiles all of Florida's bromeliads, but also describes how they manage to subsist on larger woody hosts without operating as parasites . . . ."
Every bromeliad lover, especially those raising tillandsias as many of Florida bromeliads are tillandsias, will want to have this book in their library. It professionally discusses every bromeliad species--forms, varieties, and subspecies--found in Florida.
