This is a wooden Erica, Erica arborea. They grow wild in Italy and can be great bonsai material. The deadwood is worked on, of course, they don't look like this in nature. The tree stands in kanuma like an azalea and should be treated like one. They hate to be wired and bent. So I use guy wires. Overwintering like olives or azaleas, cool, very little or no frost. this tree might be available for the right offer.
