So I got my little red wagon out, filled it with plant material and headed to the backyard.
Looking at the photo at the top of the page you see a wide open palette. Along the left side of the garden area, down towards the water is a very shady area. This is the place that I planned to put a sea of ferns, Autumn Ferns. I put a Witchhazel in a week or so before, in an area that gets some dappled light. This Hamamelis x intermedia Feuerzaube gets large, so I gave it lots of room. In my planting/planning I have considered mature sizes and spaced accordingly.
I spread the ferns out, looked from many angles, adjusted as needed and set about planting. I think the plants kind of disappear once they are planted. Next spring when they put forth their golden new foliage it will stand out .
