How Big Does a Peanut Plant Grow?

The peanut plant, scientific name Arachis hypogaea, belongs to the legume family. It's an annual plant that produces peanuts.
  1. Size

    • Peanut plants typically grow up to 2 feet tall, and plants can spread 3 to 4 feet across.

    Features

    • Peanut plants have green stems and green, oval-shaped leaves. They produce small yellow flowers that are self-pollinating.

    Function

    • The peanut plant's flowers bloom for only about half a day. A few days later a stem will grow from the flower and bury itself in the soil. Each stem will produce a peanut.

    Geography

    • The peanut plant is native to South America but now grows in warm regions around the world.

    Considerations

    • A peanut plant can be grown from any raw peanut. Simply plant the peanut, with or without the shell, in 2 inches of well-drained soil. Keep it warm and moist until germination. It typically takes three months to produce peanuts.

    Misconceptions

    • Peanuts aren't actually nuts but seeds or kernels.
