Manyflower beardtongue(Penstemon multiflorus) (also known as White beardtongue) is a deciduous perennial wildflower. It blooms in spring and summer and occurs naturally in flatwoods, sandhills, scrubby flatwoods and ruderal areas. Manyflower beardtongue is almost endemic to Florida, with only a few populations in Alabama and Georgia. It attracts a number of pollinators, including hummingbirds, and is the host plant for the Baltimore checkerspot (Euphydryas phaeton).

The plant’s showy white to light lavender flowers are born in terminal panicles on oppositely arranged stalks. Each flower is 5-lobed, 2-lipped and tube-shapedCalyces are 5-lobed and hairy. Stems are erect, reddish in color and emerge from a basal rosette of large, grayish-green leaves. Stem leaves are sessile and oblong to lanceolate with entire or slightly toothed margins. They are oppositely arranged and become reduced as they ascend the stem.

The species epithet multiflorus is from the Latin multus, or “many,” and florus, or “flower,” and refers to the many flowers born on each flower stalk. The common name “beardtongue” refers to the tendency of blooms within the Penstemon genus to have a long, often hairy filament that protrudes from the mouth of the corolla, giving the appearance of a fuzzy tongue.
