Thanks, Scott.
I also own 'Chocolate Queen'. At some point in the past, someone corrected me saying it was 'Mocha Latte'. I liked that name better, but when I Googled it I was faced with the names you mentioned (and maybe more). Knowing Ti plants vary with the amount of sun they receive and other culture conditions, as well as the time of year the photo is taken, it was all very confusing. And knowing the wealth of misinformation and mis-ID's freely available on the internet, I just gave up and kept the original ID.
These two Cordylines, along with my Cordyline 'Electra' came as cuttings with "probable" ID's. In researching on the internet I was never able to absolutely confirm or refute any of the ID's. It sure would be nice if Cordyline cultivars were legally registered.
By the way, are you (or anyone else) familiar with the rather nondescript brownish Cordyline out front of Disney's Polynesian Village Resort in Orlando? It is near the sidewalk, and I believe the only Cordyline in the bed. In April of 2014 I nicked a couple berries from one of the clusters of seed on the plant and ended up with four seed-grown plants.
All are different (of course) and three of them are quite nice! The fourth needs to be moved into a better situation, but recently started showing some nice red streaks in the new leaves. The first three are blooming this year. I would love to put a parental ID to these plants.
