Tillandsia recurvata

Tillandsia recurvata, commonly known as small ballmoss or ball moss, is a flowering plant (not a true moss) in the family Bromeliaceae that grows upon larger host plants. It grows well in areas with low light, little airflow, and high humidity, which is commonly provided by southern shade trees, often the southern live oak (Quercus virginiana). It is not a parasite like mistletoe, but an epiphyte like its relative Spanish moss. Tillandsia recurvata derives mainly physical support and not nutrition from its host; it photosynthesizes its own food, absorbing water that collects on its leaves. It obtains nitrogen from bacteria, and other minerals largely from blown dust. Though not a harmful parasite in the same sense as plants such as mistletoes that feed on the sap of the host, ball moss may compete with a host tree for sunlight and some nutrients, and by restricting available surface area for new branch sprouts; however, except on stressed host trees (e.g., in some urban settings) it ra......read more on Wikipedia.
