I've got Autumn Joy Sedum all over and the oldest ones sprawled out and laid flat. I've never watered them -- let nature do it -- and I didn't change that this year, maybe that was the issue. The ones that sprawled are about 7 years old. They younger ones didn't sprawl, but they weren't as big either. They are still blooming beautifully, but the center is just stalks splayed out.
Is this time to dive or just strange weather this year?
