What can I say ?
The paving for our drive way has been there eleven years .. the ostrich fern .. well about 5 or 6 years ago I started out with ONE plant ... but they are usually gentle souls .. smell heavenly .. fill a green space in deplorable conditions and never complain .. ( now look down at the bottom of this picture and scroll to the next ) ..
.... they make me wonder how determined and muscular they truly are ??
Nature will happen where ever it WANTS to ?
