I got an Arisaema griffithii tuber over two months ago. I potted it when I got it and after a month or so it was clear it wasn't growing. I thought the medium was too moist so I repotted it in something better draining. In the process I was surprised to see that it had grown some roots, the central, main bud covering had dried up and come off and several buds encircling it on the top of the tuber were looking like they wanted to grow. Now, some time later, still nothing has shown above the medium. This plant seems to behave differently from my other Arisaema species. Should I let it just dry out and wait until it shows signs of wanting to grow on its own? Or what should I do?

Thanks for any information or advice you can give.
