My 'Plants of the Pacific NW' field book includes both native plants and those which are introduced non-native invasives, I suppose as a means to ID what might be found out in the wilds. We had a previous discussion about listing invasives as a checkbox in the database, but that became too confusing because what might be invasive in one region may be perfectly behaved in another. It was decided to keep that information in the comments. Might be the same can of worms with natives - how far back does one go? I include native information in the comments section, and try to clarify that a certain plant is native IN my region as opposed to native TO my region, two very different meanings to me. I do agree that place of origin would be helpful in the database - to more easily determine if it is a native in your area, to have a better idea of the plant needs, and for a bit of history.
