When I am at my cabin I do not miss the opportunity to visit my favorite deciduous wood of oak, apple, wild cherry, hazel etc. At this time of the year the wood floor is covered by Hepatica nobilis, Anemone nemorosa and many more spring ephemerals.
Incredible display! Our forest floor is boring...too many conifers so just lots of moss!
Trond, your forest floor photo looks like a fairytale setting.
For my area, a deciduous forest floor completely devoid of any underbrush like your picture is usually devoid of wildflowers too. Main exceptions are Big leaf asters in the north, and Cardamine laciniata in the south. Both poor or non-bloomers in such a situation.
Lovely! As I've mentioned on SRGC forum, I love this kind of forest (at least in spring!), which is like nothing here--our deciduous forests do not have a closed canopy, so undergrowth is heavy--there are many flowering species, but no one gets this kind of space to itself! And very little here flowers in the woodland in early spring...
