Beautiful Citrus Archway

i was italy last month; Ravello, high up on the Amalfi coast and saw this the gorgeous archway formed with trained Lemon trees. I know we cannot leave them in situ outside in winter in this country, but inside the conservatory either side of the entrance is a perfect spot. Easily trained, Lemon, Lime or Orange trees can be used just like other fruit trees. Can you imagine the scent as you walk through it?!
