Nasturtium prefers well drained, low fertility soil with full sun. Hyacinth bean or Dolichos lablab, is another great, attractive vine for hot, dry areas. The vines can grow up to 30 feet long, but are usually around 15 feet. The vines can be used as a ground cover or used to cover a trellis or fence. The leaves have three leaflets that are broadly oval, coming to a point at the tip.
Hyacinth bean requires warm soil to germinate well, preferably with well drained, evenly moist soil.
