Parthenocissus quinquefolia, Virginia creeper.
Various carnivorous plants (Sarracenia spp.) and other weirdlings. The mossy stuff is Sagina subulata; Scotch (or Irish) moss. Not actually a moss.
Sarracenia sp. These are water-loving bog plants.
The dark purple is Eucomis comosa ‘Sparkling Burgundy’. The soft silvery-green thing between the Eucomis is Potentilla peduncularis. Makes a yellow flower. The spiky green leaves in upper right belong to an Iris.
Citrus trifoliata ‘Flying Dragon’ – Japanese bitter orange. Spiny. Will get much bigger if not pruned assertively (you can see evidence of hard pruning here).
At right, Bletilla striata ‘Alba’, Top: Melianthus major (this guy will need to be moved). Left: Carex sp?
Tall stuff on right is Canna. Flower will tell which. The variegated shrub I believe is Cornus alba.
The small bronze palmate leaf in lower left belongs to a Rodgersia; the taller strappier leaves just above it I *think* are Lobelia tupa, and the huge flat leaves are Podophyllum pleianthum.
Lobelia tupa for sure. Behind it is black bamboo.
Tall plant in back: Thalictrum sp. (meadow rue). Middle plant with finely cut leaves: Syneilesis aconitifolia (shredded umbrella plant). Front, low one: Lathyrus vernus. Makes purple flowers.
Paris polyphylla. Lower left: Aquilegia vulgaris ‘Leprechaun Gold’ and Adiantum venustum (maidenhair fern).
Actaea racemosa, I think.
