Our live oaks are covered in resurrection ferns (Polypodium polypodioides). During dry periods,the ferns look very brown and very dead. But when it rains they turn green again and are so lovely.
They are air plants and only use the tree branches for support and get their nourishment from the air.
Birth, death, rebirth, support, nourishment---these are themes throughout the (ongoing) life of our Savior.
