Rehmannia elata is a
consistent performer in every garden that I have planted it. The
Chinese Foxglove will grow in full sun near the coast but really seems to
prefer some shade. I have had the Rehmannia elata naturalize and spread by
runners in a relatively dry shady location under oaks near the coast,
though they prefer some water. And can even become a bit of a pest
if too much water is available. Fortunately the run-away plants are fairly easy to
remove. Rehmannia elata has been used in Chinese and Japanese herbal
medicine for the kidneys, skin and old age. All parts of the Chinese
Foxglove are poisonous if ingested without proper preparation
