Blooming
This vine is a fast-growing plant. With proper care, you will notice white and purple flowers developing in early summer, with the flowering period continuing till mid-fall. This means that you can enjoy fragrant, purple flowers till the arrival of frost. The pods and seeds of this vine are poisonous, and they should not be ingested by humans or pets.
Collect Seeds
Since this is an annual plant, you will need to collect some seeds before it withers for planting next year's batch. This will allow you to save the money you would have spent on buying a fresh batch.
Allow the seed pods to mature and dry, while on the plant. Harvest pods gently and break them open to remove the seeds. You can store these seeds in an airtight container placed in a cool and dry area.
If you fail to collect seeds for the next season, the fallen seeds will germinate in the same growing site. With a very low amount of disease and pest incidences, growing a healthy hyacinth bean vine requires little effort.
