Cotoneaster on the rock - ISHITSUKI

I´m not sure if it´s real ishitsuki, because the plant grows right next to this stone, not in the stone. It is completely rooted in the soil in a training concreate pot. It slightly clings to the sharp stone from Croatia. In overall composition I´m trying to work with the stone as with a trunk. For the first time it bears some fruits, invisible in the pictures.

The glass of young wine as a scale and ispiration :)
