Bat Plant

I am looking for the botanical name for a 'bat plant'. I saw a post from a couple of years ago mentioning tacca baccata. I tried a search with no results. I would also like to progagate same.
Would appreciate help.
Thanks.

 

Try searching just the genus Tacca.

Here's one page with some info.

Thanks a lot!
Seems I do not have ideal soil but the plants are flowering well.
