what happens when you use a perennial such as hosta for an indoor project such as kokedama? does the perennial die back in the fall and re-grow during the winter or in the spring? How about after that? I put a mouse-ears hosta into a kokedama a couple of months ago and it died back, just as it would have had I left it in the ground; I have the kokedama under lights; it is already sprouting new growth and it is late November.

Usually, in an indoor setting, you will have to drop the duration of light it receives, reduce the temperatures, and reduce moisture to force it into dormancy. They really do benefit from having a rest period, and will prefer to have a dormancy once a year. It is likely that the plant suffered a temporary issue that has resolved itself. Whatever happened, it seems to have simulated its own dormancy. I would not expect it to do so every year. It might need some help in the future to achieve this.
