I have had a tall sedum ('Red Cauli') for a couple of years. Instead of staying in a nice clump form like 'Autumn Joy', as it grows it flops and takes up too much space. Right now it is about 18" tall and just starting to form buds. If I pinch each stem back, can I keep it looking nice and will it form new buds? I guess I want it to look like Autumn Joy but with different color flowers
