Re: [IGSROBIN] Geranium arboreum

Cannot agree more, Andrew.  Many endangered species that seem to have narrow
ecological nitches can thrive in a variety of quite different locations.
They only seem specialized because that is the open nitch they evolved to
live in.  Unless they have specialized symbiotic bacterial or fungal
relationships, or some other unusual requirement, they can do well in many
situations.  In addition, that is the only way, often, to save them for
possible re-introduction.
