The common 'Spanish Moss' is now a widespread weed species in the new world. The long trailing stems latch onto trees and power cables and form large hanging clumps.
I am hoping that it will be hardy enough to survive in a cold greenhouse - when I move it into warmer conditions it suffers from low humidity in the winter and
takes a long time to recover.
It was a surprise to find the clump in flower, though I have found an old seed head tangled in it before, so I knew that it did flower.
The individual green flowers are tiny but wonderful.
