Wisteria

This year our wisteria has bloomed more than it ever has before, more than several years together, and it smells gorgeous too.  It's not good blooming in comparison to most wisteria plants but it's good this year.  It's not a happy plant in that conservatory; it would be better exposed to the elements again, and goodness knows how it get enough water because though it leaks in there, it's not like there's ever a deluge of rain water.  However, since we have a well in the garden and a well in the house, I wouldn't be surprised if there's an underground stream from which this wisteria can feed.
Apparently, Victorians used to plant a wisteria next to a new house - I wonder why. I suppose this wisteria was planted circa 1902 when the sitting room was added to the older part of the house.
