I, too, love hyacinth beans. I started mine a few weeks ago and they're already starting to "vine". We have a large deer population here in central Texas, so gardening is a challenge. Knowing how the white-tails love vines, I planted several five gallon pots and have put them in the unused dog kennel. I call it The Vinery.
The six foot chain link will act as a trellis, and the deer can't get to them. Am growing passion flower, queen's wreath, cardinal climber, cypress vine, morning glories, moon flower, and - of course - hyacinth beans. I know there's a white variety, but the seeds offered online are ridiculously expensive. Anybody have some to trade?
