Good for you, Caesar! I was able to find D. trifida yams at a local Hispanic grocery (from Costa Rica) and planted them immediately, hope they sprout. I did meet someone with the D. bulbifera here in Florida. The main advantage he explained to me was that you can grow them as a perennial, leaving the root portion permanently in the ground, and just harvest the bulbils. Sfter the first season the in-ground tubers become very vigorous and produce large numbers and large size bulbils. It seems that other yams including alata do the same as far as bulbils are concerned. Last year I got no pruple Ube alata yam bbulbls and di harvest all but this year I may save 1/2 my crop in-ground to attempt looking for the 2nd year bulbil crop. My ordinary alata bulbils did grow out very well last year so what I am seeing is that it makes sense to keep a "mother" yam going which might make multiple bulbils each year to use as planting material.
here is an example of a central Florida purple alata yam in it's second year and resulting bulbil crop:
