Penstemon 'Cotton Candy'


Add to wishlist Remove from wishlist
Sweet hybrid between two of the best Washington natives, Penstemon rupicola and P. barrettiae. This is growing in our rock garden where it excels in poor, well-drained, sandy soil in full sun with minimal water. Nice evergreen leaves and big sugar pink flowers in summer. Ours came from the Columbia-Willamette Chapter of the North American Rock Garden Society.
