You are probably going to see that all the old Univ. of Florida and younger Mississippi State Univ. PD-resistant bunch-grape releases are hard to find by mail order, and harder still to find already rooted (i.e., not merely cuttings). I searched a year or two ago myself and am still looking for some of them.

If no one else answers, in the next few days I may be able to find record of where I got my "Conquistador" a year or so back. Unfortunately the very limited number of cuttings available this winter from it are already promised.

Thanks "gonebananas".
Since you got your "Conquistador" a year or so back, have the vines produced any grapes?
How do they taste?
How about the acidity level?
Are they sweet?

It was last fall now that I think of it and they have not fruited yet. The plants were healthy and potted, but small, little more than rooted cuttings. Some other much-larger well-rooted though bare-root bunch grapes obtained just a little later, in winter, did in fact fruit the first year though.

I am almost positive I got my "Conquistador" from these folks, though I don't see mention of shipping now in a brief glance at their site. The plants were in containers in artificial soil so some interstate problems are eliminated. Email them via their "Feedback" page if interested. They have other hard-to-find PD resistant bunch grapes too.
