moss tendrils twine

unharmed by winter wind and ice

needing nothing more

Spanish Moss is very common in our area of the Texas Gulf Coast, and in many  areas of the South. It is not a moss at all, but kin to the pineapple. It needs only the moisture in the air for thriving. A freeze does little damage, so in Spring it comes back and continues to grow.  Ice build up might make it heavy enough to fall to the ground.  But if it does end up grounded, it is not dead. Tossed back to the trees,  it will thrive again.  Thinning it actually helps it grow.
