I have often thought that the cultivar doesn't really matter. Its what color you like. They only come in such a limited range, or as singles/doubles/triples. Pink, Salmon, yellow, creamsicle orange and white are it.
If I had to pick ONE, I would pick CULEBRA because it has unusual leaves. Its white. I have grown may drugs, we used to trade for them all the time and there was a lady here in my area who hybridized her own. Mine now are all the plain old standard Ecuador Pink which is a great old standby. But even in a container they can get tall tall tall. Mine are unground and are over 12-14 feet tall.
But its easy to keep them at a more reasonable height, all you need to go is prune them every winter a few weeks before you plan to bring them in. This also encourages branching.
They tend to drop leaves in winter anyway, and indoors I am sure they will drop leaves. But they come back fine ind Spring.
I have a small Culebra that I got in a trade a year ago, its still in a container in my greenhouse and I think I am going to leave it there.
