Eventually a Wisteria Trellis

(The excellent public park right across the street from the private Kiyosumi Garden.) 

Unlike the wisteria I saw in Kagurazaka the other day, this tree is nowhere near blooming. The buds look more like lavender at this stage.  

But in a couple of weeks, you won't even be able to see all the wooden slats.

 

The poor tree is being fed to the roof.
