Scrophulariaceae (Figwort Family)

This is one of the few fragrant penstemons. Its sub-woody, branched stems bear oblong, grayish leaves which ascend the stalk in fused pairs. A few sparsely-leaved, erect, stout stems have swollen white to reddish-pink bilaterally symmetrical flowers mostly turned to one side in a long, narrow cluster. Flower spikes can reach 4-5 ft. in height.
This is one of the most delightful species of Penstemon. Its cheery puffed-up flowers are exquisitely fragrant.
