I have 100 year old wisteria vines; one blooms, the other does not. Is one a male the other female? I'd like to remove the non bloomer if it is not necessary. I've taken cuttings from the bloomer and they are now blooming less than 3 years from planting.

You do not need both for this plant to bloom. Even if there was either a male or female plant, it would still flower without the aid of the other. These plants are notorious for non-blooming issues.
