Tillandsias - The Air Plants

Tillandsia with red foliage

Members of the Bromeliad family Tillandsias are a fascinating group of plants commonly called 'Air plants'. And although they do grow ' in the air' they do not actually live on air alone.

These plants have a sophisticated system that allows them to use scales on their foliage to adsorb not only moisture, but the nutrients required for growth and survival.

They do have root systems, however in the natural environment they use these to attach themselves to trees and sometimes rocks, the do need moisture and in many ways the trees help provide this.

With well over 500 species it is a little daunting to choose the best varieties, however this will depend a little on your climate. The natural habitat ranges from tropical rain forests to near desert conditions.

The varieties with denser (more scales) or coarser silver foliage and thick hard stems are usually the desert or dry climate varieties. Those with finer and greener foliage are generally those from the tropical or rain forest areas.

We also have size variations from plants to much larger specimens. And although they are said to be slow growing, which is generally tree, some will grow a little faster than others.

Flowers vary as well from the spectacular such as those on Tillandsia dyeriana, to rather small and almost insignificant flowers.

Air Plants or Tillandsias are a popular and easy going Bromeliad readily available for sale online.

For many gardeners it is a little hard to accept that these plants do not really require fertilizer, they don't, however it can be beneficial in some circumstances.

In terms of plant care like all Bromeliads Air Plants do not like frost and will require some protection. Air plants can be a great cover for a shady garden wall and could be a star attraction on a vertical garden in a shaded position.

Propagation

Tillandsia can be propagated from seed, and if you have fresh seed you will usually be successful.

You can sow seeds of a fine wire mesh or indeed on any medium that allows good air circulation. Seeds will germinate quickly however seedlings are very slow to grow into good sized plants.

The seeds need good filtered light, highhumidity and good air circulation to germinate without setbacks from fungal diseases.

It is much easier, and quicker to seperate offsets, wait until they are 1/3 to 1/2 the size of the parent plant. They can then be soaked in water and mounted.
