A chocolate tree (Theobroma cacao) is a large plant, not starting to flower until it reaches 5 to 7 feet tall. It craves warmth (temps above 60 F) and bright light. Sit it outdoors for summer to encourage flowering. Blooms typically form spring through fall, followed by a large pod-like fruit. The fruit starts green and ripens to golden yellow. Inside the fruit are the chocolate beans, which must be fermented and dried before use.
