I have had a wisteria for quite a few years and it blooms once a year. This year it is starting to bloom again but it is the last week in July. I am not complaining, but I would like to know why it is blooming so late in the summer. Thank you.

There may be environmental reasons. Not a long enough or cold enough dormant period.
If the plant seems healthy otherwise, I would not worry.
