Man, some of these semps are pretty darned prolific. The two large clumps towards the bottom of this picture are my first two acquisitions. I pulled some chicks off and planted them around to help fill in and even those chicks are having chicks. It's a total chick-fest. I have read in this forum that 'More Honey' is prolific, but in this picture at the upper left it is doing OK but still may get shoved out of the way.
I have no problem with these semps covering all of the available soil, that's my intent actually, although it would be nice to see the rock outcroppings. But my question is about maintenance. What happens when these semps all bump into one another and run out of space? Does it all just take care of itself? Or do I need to go in and do some selective removal? Will they try to overrun each other? Will they go vertical?
It seems like plants are healthiest when they have room to grow. But maybe evolving in alpine rock crevices has made these guys different?
