  • Description & Ethnobotany
    • Plant Morphology :
      Growth Form: Small tree up to 4.6 m tall in the ground.
      Foliage: Elliptical to oblong leaves are arranged in pairs. New foliage is reddish brown, while mature foliage is olive green.
      Stems: The 4-sided stem has thin, wrinkled wings at the stem corners.
      Flowers: Reddish pink flowers are about 2.5 cm wide. They occur solitary or in small clusters of 2-3 in the leaf axils (the place where the leaf stalk intersects with the stem).
      Fruits: Oval to pear-shaped, pungent fruit has glossy, reddish brown to nearly black skin with pinkish red flesh.
      [Others]: This cultivar is popular in India and South America.
      Cultivation :
      Young, growing plants should be watered daily, while mature, fruiting plants should be watered less frequently, such as a few times a week. The plant typically begins to fruit after 2 years. It's a good practice to remove some of the flowers to concentrate the plant's energy resources on a smaller number of fruit, allowing them to become bigger. Regular pruning to thin the crown will help to prevent diseases caused by bacteria and fungus. Cover the soil with organic mulch to moderate soil temperature, as well as provide additional nutrients. This plant is susceptible to scales and whiteflies which can be controlled with an insecticidal soap.
