Growing Capers

Growing Capers Amazing ...
Just loving the cooking classes at the agrotourisum Masseria Montenapoleone as it also touches on my passion the edible garden.
On our garden walk today and picking things for the cooking class we come across my first ever sighting of Capers and they are growing here naturally. They are growing like weeds, with a pretty white flower and long purple stamens on long cascading branches with lush green leaves.
 The ants carry the seeds into the crevices of the limestone and from a small stone hole on a rocky wall or natural outcrop comes this amazing plant surviving in what appears to be no soil at all.
 Hmmmm must look into how I may be able to recreate this stone wall affect back at The Retreat as we do have a very similar hot and dry climate "except for the humidity" so very well may be able to grow them back home in a pile of limestone.
Here the winters get down to sometime 6 deg over night and sometimes even a frost, but as the plant is deciduous maybe it's still worth a shot even though we get a month of frosts. Perhaps the rocks will warm enough during the day so a mission is now planed so lets give it a try.
