Kids love Valentine's Day candy. Yet, there comes a point when all the conversation hearts and chocolate cupids handed out at school lead to too many meltdowns. Instead of the go-to doily-topped valentine, consider this lima bean plant that reveals an "I Love You" message when mature from Hearthsong. It's a valentine that shows its love long after Feb. 14. Plus, kids will have fun caring for their plant and watching it grow.
