Chinese foxglove (Rehmannia angulata, formerly R. elata) looks like some sort of exotic conservatory plant, but it’s actually pretty easy to grow as an annual, either in the ground or in a container. Low rosettes of deeply veined leaves send up dark stems that typically reach 18 to 24 inches tall, with rich reddish pink, yellow-centered, trumpet-shaped, lipped blooms. I grew this for the first time in 2020, from indoor-sown seeds, and it flowered from midsummer to early fall. Where the plants are perennial, they apparently bloom mostly in late spring to early summer. Deadheading may extend the bloom period, though.
Chinese foxglove can adapt to sun (in cooler areas) or partial shade. Mine did well in a spot with morning sun and afternoon shade. This species flowers the first year from seed, so you can grow it as an annual anywhere (it may self-sow). It’s reportedly perennial in Zones 7 to 10, where it can spread by rhizomes to form handsome patches.
Harvested in September 2021. At least 25 seeds.
