I can tell my gartenmeister has a nice rootball because it is very firmly entrenched in the potting mix and doesn't move a millimeter in high wind. This plant hasn't gotten much hummer use, but late in the season, once it cooled off, it exploded with blooms and looks great. I have limited space inside so I wasn't planning to overwinter it, but I also doubt I'll be able to find it locally again next year.

I noticed the same thing with my gartenmeister that later in the season it suddenly has a ton of blooms, crazy.
