Haha! bush expert,very funny...
That does look like a citrus tree.
I would recommend going to the plant shop near Migros, on the same side of the road.
We bought citrus trees there. The young girl there is really sweet and speaks good English and will be able to recommend tall plants for pots.
Her prices are good too.
Be careful and shop around, the one on the other side on the corner further towards Calis had extortionate prices in comparison, quoting 20 tl for cactuses which we later bought for 5tl.
Zakkum trees for 15tl, again bought for 5 and so on....
We told the young girl and she said her prices are standard, same for everybody and we've been back again since.
crazy the way some places do business!
I'm glad you posted this, was thinking about getting some wood trellis / privacy screen, but now fancy the idea of tall potted trees instead.
let me know what you choose.
