Summary

This herbaceous perennial is deserving of greater use in the garden because of its cultural adaptability. Long-sepal beardtongue tolerates a variety of conditions from filtered shade to full sun and moist and well-drained to dry soils. Flowers are produced in terminal panicles and each individual flower is 1” long, snapdragon-like and ranges in color from light violet to purple. Plants can grow 1-3’ tall and roughly 2’ wide. The foliage is lance-shaped, semi-glossy, medium green and has finely saw-toothed edges. Use with Spigelia marilandica to extend the season of bloom or use with Heuchera americana ‘Dale’s Strain’ and Amsonia ciliata for a pleasing foliar combination.
