You can find less common jasmines at a number of nurseries on the web, logees, kartuz, glasshouseworks, and a few at Gardino; I've had good experiences with all of these, and I'm sure other folks can chime in with other suggestions. Just beware that azoricum is invasive in S. Florida, and could get out of hand in Texas, too.

If you want to hurt yourself by seeing species we don't have in the states, check out plantsman vine nursery in France; they have a ton of rare species, and the owner is trying to build the most complete collection in Europe!
