Habitat :Agalinis tenuifolia is native to the eastern and southwestern United States, and Canada, which produces purple flowers in late summer or early fall. It grows in moist open areas and low woods in Texas.
Agalinis tenuifolia is a perennial plant .It is erect, annual, 8″-24″ tall forb, dark green, blackish when dry, many erect branches; stems smooth.Individual flowers and their buds are produced from the axils of the leaves on the upper and outer stems; these flowering stems can be regarded as leafy racemes. The swollen flower buds are conspicuously white. Each flower is about ½–¾” across, consisting of a short tubular corolla with 5 petal-like lobes and a tubular calyx with 5 short teeth. The corolla is pink, purplish pink, or medium purple; its 5 rounded lobes are quite large in relation to its tubular base. The lobes are finely ciliate along their margins. The lower interior of the corolla has dark purple spots and a pair of faint yellow lines. Near the upper interior of the corolla, there are 4 stamens with hairy white anthers and an undivided white style (sometimes with a pale yellow tip). The slender pedicels of the flowers are green to reddish purple; they are usually as long or longer than the flowers (at least ½” long). The blooming period occurs during the late summer or early fall and lasts about 2-3 weeks. Each flower lasts only a day or two before its corolla falls to the ground. There is no noticeable floral scent. Each flower is replaced by a globoid seed capsule containing many small seeds that can be blown about by the wind. The root system is fibrous. Slender False Foxglove is partially parasitic on other plants.
