Answer: Dolichos lablab, or Hyacinth Bean, is a perennial vining plant that's generally grown as an annual. The plants require full sunshine, regular water, and well-draining soils. Perhaps your soil needs to be amended with aged compost (or other organic matter) to help it hold just the right amount of water and yet drain well. Try planting them again this year and be sure to choose a sunny spot. Water deeply once each week (more often if the weather gets really hot). Better luck this year!
