A conspicuous, broad-leaf perennial, white penstemon makes a spicy, cinnamon-scented show for autumn and early winter. The plant has gray-green leaves, which are deeply ribbed. They turn brick-red or purple in cold weather and attract hordes of Japanese beetles to riddle their leaves with holes.The flowers of White Penstemon are similar to Foxglove Beardtongue (Penstemon digitalis) but the latter has much longer flower stalks arising from the leaf axils and is generally a larger plant, reaching heights of up to 5 feet. All Penstemon species were formerly in the Scrophulariaceae (Figwort) family, but are now in Plantaginaceae (Plantain). nstemons that thrives in clay. The white flowers bloom for a month or longer, and look great with the blue flowers of Ohio Spiderwort and Blue Eyed Grass. Only three feet high, this clump-forming perennial does well in full sun to light shade, and tolerates seasonally damp conditions. The tubular flowers attract long-tongued bees such as bumblebees and mason bees, as well as hummingbirds. Other common names include Foxglove Beardtongue and Mississippi Beardtongue.

Whorl-like clusters of 2 or more trumpet-shaped flowers on a short stalk arising from leaf axils in the upper plant. Flowers are white, up to ¾ inch long, the lower lip with 3 downward pointing lobes of similar size and shape, the upper lip erect and lobed in 2 parts only slightly smaller than the lower lobes. All lobes may be a bit wavy around the edges. Inside the tube are several reddish or purplish lines that act as nectar guides, 4 black-tipped stamens hugging the upper part of the tube, and a creamy style.Leaves are somewhat variable. Basal leaves are stalked, mostly toothless, hairless or somewhat hairy, narrowly spatula shaped to oblong, to 2½ inches long and ¼ to ½ inch wide, with a blunt or rounded tip. Leaves become stalkless and more lance-like up the stem, pointed at the tip and often with small teeth around the edges, oppositely attached. Stems are glandular-hairy near the flowers and more softly hairy near the base. A plant typically has 2 to 5 stems arising from the base.

Large, white, foxglove-like flowers emerge from pink-flushed buds from July to October and really sing among the lance-shaped, bright green leaves. If deadheaded regularly this wonderful white penstemon continues flowering until the first frosts. It's a handsome, easy-to- grow perennial that will quickly form large, leafy clumps and is perfect for lighting up the middle of a partly shady, well-drained border. Grown in sun, it looks particularly good with silver-leaved plants. The information that is presented on this page is based on research we have conducted about this plant in our library and from reliable online sources. We also consider observations we have made of it in the nursery's garden and in other gardens we have visited, as well how it performs in our nursery crops out in the field. We incorporate comments that we receive from others as well and welcome getting feedback from anyone who may have additional information, particularly if they know of cultural information that would aid others in growing Penstemon 'Holly's White'.
