Penstemon digitalis, white beardtongue

This spring-bloomer is 2-4’ tall and does well in full sun to part shade.  It is a favorite of bumble bees, whose back-ends are frequently seen sticking out of the flowers.  

This species may cross-pollinate with Penstemon smallii, which is typically a bit smaller with smaller leaves and pink flowers. 


Phacelia bipinnatifida, fernleaf phacelia

Phlox pilosa, downy phlox

Pycnanthemum incanum, mountain mint

This perennial gets to be about 5' tall and wide.  Above the uppermost, whitish leaves are  produced clusters of small, pale lavender flowers from summer into the fall. If you love pollinators, you must have this plant!  It attracts more pollinators than any other plant I've ever known.  

Rosa carolina, Carolina rose or pasture rose

This sun-loving plant will spread to form a low thicket. It is perfect as a beautiful additionfor a slope where erosion protection is needed. 


Rudbeckia fulgida, black-eyed susan or orange coneflower

Rudbeckia laciniata, cut-leaf coneflower


Rudbeckia subtomentosa, sweet coneflower 

Rudbeckia triloba, brown-eyed susan


Rubus idaeus var. strigosus, domestic red raspberry

This sun-loving plant is a good producer of yummy edible raspberries, for you or for wildlife, in late spring-early summer and then it will produce a lighter crop in the fall.  Stock of this plant is derived from a "hand-me-down" plant I received from a friend in 2009.   It loves sun but does quite well in part shade.  It tolerates drought well, though the berry crop is lighter with less water.  It will spread, but its offshoots are very loosely and shallowly rooted, easy to remove if it spreads outside of its designated area.
