Purple Bean Hyacinth Takes Over Deck

This is a new plant my wife tried this year. She planted some seeds in 2 gallon pots on the corner of the deck. After a slow start, the vines exploded to cover about 20 square feet of deck. This vine has a bunch of small pink and purple flowers that turn into seed pods (picture below) after the bloom fades. So you get to enjoy great green foliage, delicate flowers and beautiful seed pods.
The seed pods are unique in that they have a zipper down one side so you can easily remove the seeds for planting next year.
