Lori, that's a difficult question you have asked. Aegyptiaca
these like Acacia nilotica subs. indica can be local. That other Salvia can also be local. Look at the terrain
no city for miles.
Mirabilis jalapa is the fly in the ointment for which a study of British history and their activity in the area will have to be looked into. There is an Acacia in the ID forum which after a month of checking the only conclusion that could be drawn is that it is a Australian variety. In spring Cosmos and Daisy will be in bloom in the mountains, that again is British activity. I will be posting pics in spring. Bearded Iris is ours
Opuntia is again British activity, they brought it to protect the railway tracks from stray cattle while Euphorbias are ours.
Difficult question is all that I can say and it requires a lot of work. Most of it in records.
Remember these Alps in Europe meander across North Turkey then connect here with the Himalayas. So plants from Europe can be also found here. Then the North African belt(plants) also ends up here. Look at the regions on Tropicos you may get some idea of the complexity in the question. Then plants with indica in their nomenclature do not spread North. Here we get plants with chineninsis in their name which means the indica belt is left South.

The above are all growing in the wild but are named cultivars so I can say they are garden escapes.
