The common name of perennial
flower Rehmannia is Chinese Foxgloves, because the tubular flowers bear a resemblance to Digitalis. They do well in shade, even dry shade. And these foxgloves, although not as hardy as digitalis, are repeat blooming throughout the growing season.
Common Name(s): Chinese Foxgloves
USDA Plant Hardiness Zones:
24 - 36" H, 18 - 24" W
Repeat blooms spring through fall
Spikes of hanging bell-shaped, rose-pink blossoms poke up from scalloped, glossy green leaves. Unlike traditional foxgloves, the petals of the bell lip flare open and outward. The prolific blooms are long-lasting and will repeat bloom for 3-4 months. Spring planted seeds will generally not bloom the first year. Seed can be started in the fall.
Rehmannia help to light up shade gardens and begin blooming as spring woodland flowers fade. They provide a nice accent to Hosta
and the glossy leaves and nodding blossoms contrast well with Astilbe
. Rehmannia also grow happily in containers, if given regular feedings to encourage blooms.

Cultural Growing Notes:
Chinese foxgloves grow best in light shade, but can handle full sun if there is sufficient water. They are more drought tolerant in the shade.
Maintenance: Plants should be deadheaded for continual bloom. A rich soil or monthly feedings will also help promote flowering.
Problems & Pests: Although Rehmannia is generally pest free, it can become invasive in certain areas, particularly when grown in moist, rich soil. If your plant starts to become aggressive, either cut back on food or water.
