Rehmannia elata is commonly called Chinese foxglove for its resemblance to foxgloves, but this herbaceous perennial is actually a member of a completely different family, Orobanchaceae.  Although this plant is native to China, Chinese foxglove thrives in the warmer climate of North Carolina and is a lovely addition to local gardens.

Rehmannia elata grows best in loose, moist, and well-drained soils. It prefers part shade, especially appreciating the morning sun and afternoon shade during hot summer days, and it also tolerates almost full shade. Once established, it is also drought resistant. However, be sure to protect it from freezing temperatures during the winter with a good layer of mulch. Chinese foxglove is also generally pest-free, attracting only the occasional slug or snail.

Unlike true foxgloves, Chinese foxglove will repeat bloom for 3-4 months, usually unfurling its bell-shaped petals from May to September, with the heaviest bloom around June and July. It is generally low maintenance, but if you want to see it keep blooming, you’ll have to remove its spent flowers. However, this little bit of work is well worth it. Its attractive rosy purple color is sure to brighten up any shade garden.
