I think everyone likes Semps, whether they are growing in a pot or in a rock garden. There are so many varieties from which to choose too, which is also nice. You can really get a good colourful display going with all the blues, greens, silvers reds and greens. Unfortunately, not all of them are winter hardy here in Vancouver and even bringing them inside on a southern windowsill is no guarantee since it rains for most of the winter. The southern windowsill isn't sunny is what I'm trying to say and the plants tend to get too decrepit to make it through the season. Ah well. The usual green-red ones are the hardiest around here and pay no-nevermind to rain or snow.
