Slender Beardtongue, Penstemon gracilis


Slender beardtongue is one of five species of penstemons native to Minnesota. Of those species, it is one of three found within our growing region alongside white beardtongue (Penstemon albidus) and large-flowered beardtongue (Penstemon grandiflorus). Like white and large-flowered beardtongue, slender beardtongue prefers relatively dry, well draining sites. Its growth habit is the most delicate of our native penstemons, hence the “gracilis” in its botanical name. Bloom color ranges from nearly white to an attractive lavender. Its five lobed petal, two on top and three on the bottom, along with its tubular shape gives it its classic “beardtongue” appearance as well as serving as a welcome invitation to bumblebees and other pollinators. A very drought tolerant plant once established making it a low fuss addition to any pollinator garden.
