Have you bothered to Google? Lots of sites giving growing instructions....here's one.

Yes. I’ve visited a lot of sites that have brief information like the one you linked, but I was hoping to find more details about planting media in pots, preferred pH and growth rate. I’m sorry my question was so cryptic. I used to be a regular on the old gardenweb, but left not long after Houz took over. I couldn’t figure out the proper way to search this forum for posts related to colocasia culture. I’ve grown regular elephant ears but not this one.

Growing a named cultivar is no different from growing the generic form. It does not require any different attention, specialized media (the same as you would for the "regular" elephant ears) or unique pH.

Mojito is very easy to grow. Give it good drainage and potting soil (miracle grow is fine) add a tiny bit of perlite to the potting soil. Make sure your pot has drainage holes in the bottom.

Start it out in part sun and acclimate it to more sun over a few weeks.

If you live in the desert or a very hot climate,it might like afternoon shade.

They will multiply and make lots of babies when they are happy.

These are the colocasia mojito plants I bought. This photo was taken two weeks ago, right after I received them. Four of the five leaves shown above had bent stems on arrival and died within 48 hours. But both plants have set new leaves since I potted them in a 6-inch clay pot. I am surprised at how tiny they are. They’re more like mouse ears than elephant ears. Are they likely to get significantly larger? The seller said they would be 3-5 feet tall.
