Thanks, Karen! Yes, mine have to come inside for winter too and is why I said they're in the ground for summer vacation. In Z8, it's too cold to leave Sans outside all year. This winter they'll get to stay in new greenhouse with tons of light instead of just being stuck wherever they will fit. Usually about the last thing to come inside because I wait till the last minute to send as many extras away to new homes as possible. Once I pot them back up, I don't want to mess with doing that again until the next fall.
For the first dozen or so yrs I had a pot of Sans (totally rootbound, as "they" suggest,) there was never any action, just the same old plant, looking the same from the glacially slow pace of growth. But when I started repotting often, leaving more room for new pups to grow, a lot of very quick growth started happening, and several blooms per year. As a monocarpic plant, each rosette can only bloom once, so having new rosettes growing quickly is helpful if one wants to experience blooms often. It's not necessary at all to put them in the ground for that, but I enjoy having them "as annuals" much more than something like marigolds, and don't have to worry about watering so many pots.
