The Q&A Archives: No Flowers on Dolichos Lablab - Hyacinth Bean Vine

Question: I purchased a packet of your Hyacinth Bean annual vine and no flowers have been produced. It gets plenty of sun and adequate moisture. The vine is growing vigorously but NO FLOWERS.

Answer: This vine needs a good long and hot summer to do its best and it will climb from 15 to 30 feet in one season. It is very popular further south but as you have discovered, it often begins blooming quite late in the season when grown in cooler climates. Some gardeners will start it indoors 6 to 8 weeks before the last expected frost date in order to accelerate the bloom schedule. Good luck with your vine!
