How to grow

Cultivation

Plants need no compost; they are glued or wired to a support. Grow under glass in bright but diffused light with good ventilation. From spring to autumn immerse in rainwater twice a week (more in hot, dry conditions), drain well and allow to dry. Can stand outside in summer to benefit from rain, additional light and humidity. See Air plants for more

Propagation

Propagate from seed (see Air plants) or by separating offsets once they are at least a third the size of the parent

Suggested planting locations and garden types

Patio and container plants
Sub-tropical
