Species: Tillandsia (air plant)

Foray for foliage


Tillandsias make up one of the most interesting groups in the bromeliad family (Bromeliaceae). Most tillandsias are epiphytes (require no soil to grow) and are found growing on trees and rocks in their native habitats in tropical America.

There are more than 400 species in the genus Tillandsia. Many of these species have white hairs covering the leaves, which give the plants an attractive, silvery appearance. These hairs trap moisture for the plants and reflect sunlight for the plant's protection. Our native Hawaiian silverswords have adapted a similar strategy for dealing with their harsh environment.

Description: There are a wide variety of shapes and sizes in tillandsia species, from the small, viny Pele's hair or Spanish moss (T. usneoides), to some that can be more than 25 feet tall when they bloom. In Hawaii most species range in size from 2 to 12 inches across. Flowers may be purple, pink, yellow, white or red, and are fragrant in some species.

Landscape uses and care: Because of their small size and preference for growing on trees or rocks, tillandsias can be placed in many locations in a garden or on a lanai. A large cluster of even one of the smaller species is quite showy when flowering.

There are few plants as easy to maintain as tillandsias. Most prefer to grow in full or partial sun. They are drought-tolerant and don't require fertilizer. They have no serious insect pests, and because they are slow-growing they rarely require replanting.

They can be mounted on trees, rocks or cork bark, or planted in pots with a well-drained potting medium like hapu'u. Overwatering and too much shade should be avoided.
