The red-berried elder complex is variously treated as a single species Sambucus racemosa found throughout the colder parts of the Northern Hemisphere with several regional varieties or subspecies. I believe this photo is a Sambucus pubens. It is blooming in the woods at Distant Hill Gardens in Walpole, New Hampshire.
This is a somewhat common plant is this part of New England. Small red berries, that are not edible, will ripen in July. We have another native plant, Common Elder or Elderberry - Sambucus canadensis, that flowers later in the summer. The Common Elderberry has small edible black berries that make excellent jelly and 'Elderberry' wine.
Red Trillium and Common Ginsing, both native to the forest floor at Distant Hill Gardens in Walpole New Hampshire.
Vascular plants (also known as tracheophytes or higher plants) are those plants that have lignified tissues for conducting water, minerals, and photosynthetic products through the plant. Vascular plants include the clubmosses, Equisetum, ferns, gymnosperms (including conifers) and angiosperms (flowering plants). Scientific names for the group include Tracheophyta and Tracheobionta.
