This is one of those 'who knew?' deals. A bush-sized tree that grows mini pumpkins. According to Gardeners' Choice, the plant, capsicum annum, grows to the size of a pepper plant yielding 'beautiful orange-red fruits' that ripen all at the same time.' You can expect your pumpkin tree to be ready to harvest in two months, producing up to 50 pumpkins that are '4 inches wide with pronounced ribs.' How cute would this be in a pot on the patio or deck next year? One pumpkin tree will set you back about 7 bucks at Gardeners' Choice.
