Tillandsia aeranthos

This makes long slender leaved rosettes with a spiky appearance. It is spring flowering when it may produce dark blue flowers that are rather columnar in appearance. General care: This is an epiphyte which means it grows on trees and other surfaces. The leaves are covered in fine silvery scales and are able to absorb moisture from the air. They like bright conditions but not direct sunlight. They should be sprayed each day with rainwater during the period late spring to the middle of autumn. They should also be given a special air plant feed once a month. In the winter they should be sprayed once or twice a week, ensuring that moisture does not remain on the foliage. This needs a minimum temperature of 7C.
