Answer: There are only 3 reasons for bleeding heart not to flower; not enough light, overcrowding or too much nitrogen fertilizer. It sounds as though your plant is getting enough sunshine. Try withholding fertilizer. If it is planted near turfgrass, the nitrogen in the lawn fertilizer can adversely affect your bleeding heart. This is because nitrogen encourages lots of lush, green growth - but at the expense of flowers. If this describes the situation, I'd move the plant after the tops die down later this season, or very early next spring.
Good luck with your landscape!
