Capsicum is a genus of flowering plants in the nightshade family Solanaceae, native to the Americas, cultivated worldwide for their edible fruit. Bell peppers, sweet peppers and some chili peppers belong to the Capsicum annuum species, making it the most cultivated species from the genus.

Black pepper is a flowering vine in the family Piperaceae, cultivated for its fruit, which is usually dried and used as a spice and seasoning. The fruit is a drupe (stonefruit) which is about 5 mm (0.20 in) in diameter, dark red, and contains a stone which encloses a single pepper seed. Peppercorns and the ground pepper derived from them may be described simply as pepper, or more precisely as black pepper, green pepper, or white pepper.
