Both do well indoors. The sweet acacia thrives. I feel like the tamarind could do better but it's also been needing a repotting. I just don't want to do anything to it before I can get a few successful cuttings out of it. One seems to have finally taken though.
I call the foil wall my solar curtain. It makes this east facing window feel like a south facing one!
You can really see the tiny branch structure thanks to my newspaper, can't you? I haven't been successful with those cuttings either.
