Sedum telephium 'Purple Emperor' (Hylotelephium telephium 'Purple Emperor') is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Green, faded foliage
Insufficient sun or rich soil dulls the signature dark color toward green; site in full sun on lean ground for the deepest purple.
Flopping stems
Shade, wet, or fertile soil cause splaying; grow hard, or use the Chelsea chop in early summer to keep stems compact.
