The Common Juniper (Juniperus communis) is one of only three conifer species native to the UK.
Not really often seen as bonsai, when they are they are perhaps more likely to be one of the varieties developed by the horticultural trade for garden or landscape use. This example, however, is from yamadori or wild collected material. As such it exhibits some of the unique kinds of material that are seen in that sort of raw stock. Natural jin and shari for instance as well as aged bark.
It is a chuhin size bonsai at a height of 23cm. The trunk measures 3cm. across at the soil level. The branch spread is 37cm. The foliage areas need to be further refined and grown on so as to fill up the silhouette with ramification.
The pot is a hand made UK round unglazed ceramic, possibly Walsall, that measures 17×8 cm.
