Castor Bean
Plant a castor bean and then stand back. This is one of the fastest-growing, giant annuals in the garden, rivaled only perhaps by giant sunflower. By midsummer, you'll have a huge (it can hit up to 20 feet) tropical plant sporting burgundy foliage. It's a great plant to grow with kids. Be careful, though. The seeds are extremely toxic.
Wait to plant it outdoors after all danger of frost has passed; castor bean hates cool weather and won't grow well until temperatures heat up in summer.
