If you are thinking about adding nectar vines to your landscaping, be sure to consider the space they need to grow above and below ground. Some vines can produce very aggressive root systems.
For instance, the Passion Vine featured below, which provides nectar for various butterflies, including the Great Spangled Fritillary, needs plenty of room since it loves to spread out and over anything it can reach. And new shoots can also emerge from its root system. So you’ll want to give it some extra space.
Including a trellis or fence for the Passion Vine is another way to add a new feature to your garden.
