The difference between celandine and rehmannia

1. Difference in appearance

Greater celandine is a perennial herb, about 30-60 cm tall, up to 100 cm tall. The taproot is thick and cylindrical, dark brown in color, and the stem is cymose with many branches. Rehmannia glutinosa is a shrub, which is much shorter than the former, about 20 cm tall, with a more upright stem and fewer branches.

2. Difference of blades

Greater celandine has fewer basal leaves, which are obovate-oblong or broadly obovate, pinnatifid, with obovate-oblong lobes. The stem leaves are similar to the basal leaves but relatively smaller. The leaves of Rehmannia glutinosa are pinnate, the terminal leaves are lanceolate or oblong-lanceolate, and the basal leaves are obovate or nearly circular.

3. Petal Difference

Greater celandine has umbel inflorescences with obovate petals that are yellow in color. The inflorescence of Rehmannia glutinosa is a cyme with a corolla that has 5 lobes, each of which is oval.
