  • using biological resources to fullfill the needs of people and of natural systems is one of permaculture’s design principles; Bill Mollison, one of the originators of the design system, described doing this as working with, not against, nature
  • everything gardens, Bill wrote, his way of saying that living things alter their environments to suit their needs; in permaculture design, we select plant species that supply our needs while meeting the needs of natural systems.

When selecting species for use in design, consider:

  • plant suitability for your climate
  • how plants would benefit people and their environments
  • the multiple roles for plants — food, windbreak, habitat, fuelwood, environmental modification, shade, wildlife habitat, psychological, aesthetic etc
  • where to best locate the plant in a planting plan
  • any cautions such as toxicity, irritation, potential for spread in ecosystems.
