This is the single headed variety of bog cotton which likes damp ground but not ground which is completely water logged. There is a many headed form which grows in pools of water and draws up water through it's stem. This variety uses its leaves which are long and rolled in to needles, to conserve water.
I love it's hairy delicateness and the way it swishes in the breeze. It holds a promise of Summer which is welcome as May has been unusually cold and wet so far..
