Slender false foxglove is an annual wildflower that is native to woodlands, fields, prairies, wet thickets and along streams from Maine to Manitoba south to Florida and Texas. It is found throughout the State of Missouri. This is a wiry-branched plant with a narrow-ridged mainstem. It generally grows to 20” tall. It features very narrow linear leaves to 3” long and 1/8” wide. Purplish-pink flowers (to 3/4” long) with dark purple inside spotting bloom from the upper leaf axils on slender pedicils from August to October. Flowers are funnel-shaped with 5-lobed corollas. Each flower blooms only for one day. Agalinis comes from aga (remarkable) and linum (flax) in reference to a purported resemblance of this plant to flax. The specific epithet means narrow-leaved.
