Spotted St. Johns Wort

Hypericum punctatum
 
 
A native perennial wildflower that shares similarities with the exotic species, Common St. Johns Wort (Hypericum perfoliatum), but can be distinguished by its speckled appearance. It has prominent black glands on both its foliage and petals. The plant produces dense clusters of rich yellow flowers at the ends of its stems and branches during mid-summer, a source of attraction for bees. 
 
Its natural habitat includes the edges of woodlands, prairies, and the banks of streams, as it prefers a balance of sun and shade and thrives in moist and well-drained areas. It is worth noting that the foliage of this plant is mildly toxic to mammals and can cause skin irritation.
