'Pandora's Box', is not, IMHO, worth trying to grow. It's a mini, a sport of 'Baby Bunting' which has palest chartreuse to creamy white leaf centres with a dark grey-green margin; a lighter green area appears in the leaf where the white and green meet. I got my first one in spring 2004 and it did well at first but gradually petered out to almost nothing, though it was still alive in 2015. In 2015, I got a newer division, but wasn't thrilled with how it grew. It IS worth noting that newer versions seem to have a wider green margin than my original plant did. Now in 2016, I'm waiting to see if I lost the entire family as they were in a container and I'm not so sure it was sufficiently buried. So far no pips. Please feel free to share your pictures of this.
