This rather spectacular, muscular Japanese yew resides at the Omiya Bonsai Art Museum in Saitama, Japan, along with numerous other top tier bonsai. The pot looks like it could be Tokoname. Though you can't see the back, it's possible that the single live vein in the front supports all of the foliage in the tree's impressively massive crown.
Apologies for the bad pun in the title. We’ll blame it on faulty wiring (of the physiological type rather than the bonsai type). While we’re at it here’s another bad Yew pun.
One of the great thing about Yews (Taxus) is they grow almost everywhere. Half the landscapes the Eastern U.S. (and other places) sport a yew or two. So it’s possible to find good ones for bonsai in your own front yard (suburban Yamadori). Or someone else’s front yard (just don’t get caught… just kidding).
Another great thing about yew is they are beautiful. Especially the bright yellow green new leaves and the cinnamon bark. And they take to bonsai culture like fish to water.
The only downside is the wood is exceptionally hard. This makes carving a challenging task. Even cutting larger branches can tax (no pun intended) you tools.
Rugged tree, rugged pot. It's hard to say if the two trunks share a single root system, but my guess is they do. Another possibility is that there is only one trunk that is fused higher up behind the foliage. Like the tree above (but very unlike the tree above) it's a Japanese yew (Taxus cuspidata). It belongs to Walter Pall. It's 55cm (21.5") high and over 100 years old. The pot is by Walter Venne. The tree was originally collected in Korea.
