Moss is not a parasite and does not starve or jeopardize your
tree.
You can see these draped, beard-like plants living just as
well on fences, telephone wires and constructed surfaces. In
fact, evidence suggests they prefer dead trees to live ones.
Contrary to popular myth, Spanish Moss is a member of the
bromeliad family – an epiphyte or air plant - that has developed
a unique way to make its food. These plants have evolved the
capacity to process their food from minerals dissolved in water
that runs off across leaves and branches of the trees to which
they are anchored.
Spanish Moss is particularly suited to our region’s abundance
of lateral or radially-shaped trees (structured along horizontal
branches), which provide abundant access sunlight and moist
habitats. The plant reproduces by seeds and vegetative growth,
well-suited to seed dispersal in the intense storms common to
Florida.
Spanish Moss is a flowering plant and in spring produces a
single yellow-green and pleasantly fragrant flower on the
terminal end of a moss strand. It also provides protection for a
number of insects and other invertebrates and is a favored
roosting place for several species of bats. A number of bird
species use Spanish Moss strands as a major nesting component.
The parula warbler and Baltimore oriole actually weave strands
into egg sacs and hammocks from their newly-hatched young.
Don’t destroy Spanish Moss because of a fanciful legend.
Rather, use it as an indicator of the health of your trees.
Green plants are indicative of a robust environment. By
contrast, colonies of gray plants on a single tree suggest
moisture or other environmental stress.
Ball Moss (Tillandsia recurvata) is biologically similar to
Spanish moss, except for a compact, tufted, sphere-like growth
structure. A centralized mass of stiff leaves eminate from the
core, and a trichome layer gives it a somewhat spongy
appearance. Ball moss blooms in spring with conspicuos
blue-to-violet flowers. Its mass conceals a seed capsule that
releases the plant's seed cache for wind-dispersal. Moreover, it
is a similarly benign plant that does not harm trees but, in
intense proliferation, may be a sign of independent weaknesses
or health problems in host tree.
