Sweet corn root

(Goeppertia latifolia)



Goeppertia insignis (syn. Calathea lancifolia), the rattlesnake plant, is a species of flowering plant in the Marantaceae family, native to Rio de Janeiro state in Brazil. It is an evergreen perennial, growing to 60–75 cm (24–30 in), with slender pale green leaves to 45 cm (18 in), heavily marked above with dark blotches, purple below. Goeppertia insignis prefers indirect sunlight. These plants want well-drained, but moist, soil. They like a pH of 6.1 to 7.3. The plant requires a minimum temperature of 16 °C (61 °F), and it is commonly used as a houseplant in temperate regions. The bottom side of the leaves are purple, with the adaxial surface having what look like dark green alternating large and small leaflets overlaid on the light green leaf. Like other prayer plants, its leaves fold together at night, and unfold again in the morning. Calathea is a genus of flowering plants belonging to the family Marantaceae. They are commonly called calatheas or (like their relatives) prayer plants. About 200 species formerly assigned to Calathea are now in the genus Goeppertia. Calathea currently contains around 60 species. Native to the tropical Americas, many of the species are popular as pot plants due to their decorative leaves and, in some species, colorful inflorescences. The young leaves and bracts can retain pools of water called phytotelmata, that provide habitat for many invertebrates. Calathea leaves are often large and colorfully patterned. The leaves are often variegated with bright colors such as pink, orange, red, and white. The underside of their leaves are frequently purple. During the night, the leaves fold up. In the morning, the leaves unfurl in search of the morning sun.This phenomenon, known as nyctinasty, is made possible by a small joint the plant possesses between the stem and leaf, called a pulvinus. Calathea flowers can be yellow, purple, and white and bloom in the summer. The flowers have an asymmetrical structure with three petals and three free sepals. Calathea bracts are often more attractive than its flowers.
