The Bolivian Rainbow Pepper is a variety of Capsicum annuum, a species of plant collectively known as chilli peppers. This variety produces fruit that is initially purple, ripens to yellow and finally becomes red when fully ripe. The Bolivian Rainbow Pepper is primarily an ornamental plant due to the different colours of its fruit, which are also edible. It grows outside in warm weather and also adapts well as a houseplant. Gardeners typically grow Bolivian Rainbow Pepper plants from seed.

  1. 1

    Grow the Bolivian Rainbow Pepper outside if you are in U.S. Department of Agriculture hardiness zones 9b and up. This plant can only tolerate mild winter freezes down to -3.89 degrees Celsius.

  2. 2

    Select a planting site in full sun. This is typically a southern window if you grow the Bolivian Rainbow Pepper indoors.

  3. 3

    Add sufficient peat moss to lower the soil pH to between 5.6 and 7.5, as the Bolivian Rainbow Pepper prefers acidic soil. This plant can generally tolerate poor soil as long as it has good drainage.

  4. 4

    Plant Bolivian Rainbow Pepper seeds after the last expected frost if you grow them outdoors. Plant the seeds at a depth of 1/2 inch and space them at least 2 inches apart.

  5. 5

    Water Bolivian Rainbow Pepper seeds with 1 inch of water per week. Ensure the soil does not accumulate water, as this plant does not tolerate wet soil. The seeds should sprout within 2 weeks.

  6. 6

    Remove the weaker Bolivian Rainbow Pepper plants as they grow to achieve a final spacing of at least 18 inches between mature plants. These plants require 69 to 80 days to reach full maturity, and the peppers are ready for harvest when they are dark red. Mature Bolivian Rainbow Pepper plants require little maintenance from this point.
