I believe that Sepp Holzer does not provide any listings of seeds, as what works for him in the Alps wouldn't work in Key West, nor in Singapore, or Tuscon. His attitude is to 'just try it, and see if it works'. Modify it until you find a combo that works well for your region/climate.
Mixing the plant families is important to the mix. A hundred tomato varieties (or 100 legumes) does not equate to a polyculture. The more plant families you can provide, the more diverse your soil food web becomes, thus bringing a greater balance to your entire system.
Regionally selected wild flowers will (a) have the best chance of surviving your climate/conditions, and (b) provide food/habitat for a wide variety of natural pollinators, plus (c) bringing long season beauty to your landscape. With trees/shrubs, you need to plan the layout. With the wildflowers, just scatter the seeds anywhere/everywhere, and wait for your long term rewards.
