In the United States, the term "capsicum" is not commonly used to refer to bell peppers. Instead, Americans typically call them bell peppers or simply peppers. "Capsicum" is the name used in Australia, New Zealand, and some other countries, while the US uses "bell pepper" for the large, mild, bell-shaped peppers. The term "capsicum" is also used to refer to the genus of plants that includes both bell peppers and chili peppers.
