Tillandsia Usneoides, also known as Spanish moss, is an epiphytic plant that primarily relies on trees for support, and isn't parasitic in the traditional sense. Spanish moss attaches itself to tree branches and trunks, using them as a substrate to anchor itself and absorb moisture and nutrients from the air and rainfall.
While heavy infestations of Spanish moss can potentially block sunlight and hinder the tree's photosynthesis process, leading to weakened growth in certain cases, Spanish moss killing trees is a gardening myth that is rarely the sole cause of tree death.
