Penstemon serrulatus |
Penstemon serrulatus is a species of penstemon known by the common names Cascade penstemon, coast penstemon, or serrulate penstemon. [1] It is native to the Pacific Northwest of North America, from Oregon to Alaska. [2]
Penstemon serrulatus has multiple herbaceous stems up to 70 centimetres (28 in) tall growing from a perennial woody base. The leaves are lanceolate to ovate-oblong with sharply serrated edges. The inflorescence consists of clusters of tubular blue to purple flowers. [3]
Penstemon serrulatus is one of the few penstemons to occur at low elevations along the Pacific Northwest coast and in the Puget Sound lowlands. [1]
