Hi Art ,
I think I can help you wit a ID for the first shrub from Turkey :
Thats Styrax officinalis - I have seen this plant also in Turkey + Greece
My own expierince with this plant was not succsessful - I have bought before many years a plant from a botanical garden ...it grows well in summer ...but if comes hard winters always a part was frozen .
I have also collect seeds from a trip in Greece - they have germinatet well ...but the problem comes in winter too ...so I have given up with this plant .
They are relatet with Halesia....
I hope this helps
Hans
