Hi Lauraeli,
I am from Singapore and I have grown the black bat - Id is Tacca Chantrieri. It is a shade loving plant and love high humidity area. So , the growing conditions for the white bat Tacca is similar. However its ID could be Tacca integrifolia or Tacca Niven.

This one is Tacca integrifolia :-) it is 10 days later, and the plant is still doing ok. The room it is in stays at about 50-65% humidity. It is right next to a north window.

I have been cautious with it so far- I have watered it just once, and have not repotted it, as it seems to have lots of room still for the roots. The soil it is in has not dried out at all. Two of the small bottom leaves were yellowing, so I removed them. Other than that, it seems to have just the very tip of a new leaf showing. I dont think it has made up its mind yet, whether it wants to grow. I believe it is just adjusting to the new growing conditions.

I grow them in Florida. They can take more light than recommended. I would give your plant more light than a North window. An East window would be ideal. Growing inside is a challenge as the window blocks some light.

Mine grow under a large oak tree but get full East morning sun. They don't like to dry out. Wait to water until you see new growth.

I am growing the black. I think the culture is the same although I notice the blacks are more free flowering. I had over 20 blooms last year where friends, with the whites got less flowers.
