The ornamental pepper plant is grown as an annual plant indoors. Also known as the Christmas pepper plant. While this species does produce small white flowers it's main attraction is the fruit which appears after flowering.
We have all seen in grocery stores, eaten or cooked a variety of this plants fruit known as capsicum, sweet peppers, cayenne peppers, and chilli peppers, which this species has been bred from for ornamental purposes. The common name of Christmas pepper was given to the plant because many are sold during December and the red colorful fruits provide a festive appearance. Outdoors they fruit during the summer so the common name Christmas is not always used, which makes sense.
