Synonyms : Gerardia tenuifolia – Vahl.
Habitat : Native to N. America. Moist open areas and low woods in Texas. Woodland Garden; Sunny Edge; Dappled Shade; Cultivated Beds;
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.
Flower: purple to pink, 5-parted, 1/3″-1/2″ long, smooth inside, upper lobe arched forward over the 4 stamens the lower stamens longer; inflorescence a cluster (raceme) of flowers on 1/3″-1″ long stalks; blooms Aug.-Sept. The flowers are hermaphrodite (have both male and female organs) It is in flower from July to August.
Fruit: roundish capsule
Leaf : linear to 1/4″ wide
It is hardy to zone 8.
The plant prefers light (sandy) and medium (loamy) soils and requires well-drained soil. The plant prefers acid, neutral and basic (alkaline) soils. It can grow in semi-shade (light woodland) or no shade. It requires dry or moist soil and can tolerate drought.
Requires a well-drained soil, preferably on the dry side. Grows well in a woodland garden. This species is not very hardy outdoors in Britain, tolerating temperatures down to between -5 and -10°c. A semi-parasitic plant, thus making it very difficult to establish in cultivation. We are not sure which species it parasitizes.
Propagation: Seed –
An infusion of the plant has been used in the treatment of diarrhea.
