Don’t worry about being able to identify each of these plants (in your designs for clients). The world is full of botanists and horticulturists. All you have to do is design. You don’t have to be a botanist; you don’t have to be a bulldozer driver; you don’t have to be a fence builder; you don’t have to be an architect. What the designer has to do is look at the relationships.
One of the great rules of design is do something basic right. Then everything gets much more right of itself. But if you do something basic wrong - if you make what I call a Type 1 Error - you can get nothing else right.
That we don't design agriculture to be sustainable is totally eerie. We design it to be a disaster, and of course, we get a disaster.
I'm certain I don't know what permaculture is. That's what I like about it - it's not dogmatic. But you've got to say it's about the only organized system of design that ever was. And that makes it extremely eerie.
