Hylotelephium 'Purple Emperor' problems — and how to fix them
Hylotelephium 'Purple Emperor' (Hylotelephium '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.
Foliage greening / loss of colour
Insufficient sun reverts the purple leaves toward green. Move to a fully sunny, open spot to restore the dark tones.
Floppy centre
Caused by shade or rich soil; the clump splays from the middle. Grow lean and sunny, or apply a Chelsea chop in late spring for sturdier stems.
Crown rot in wet soil
Winter waterlogging rots the crown. Plant on free-draining ground and add grit to heavy soils.
Slugs, snails and aphids
Spring shoots are grazed by molluscs and soft growth attracts aphids. Protect early growth and wash off aphids as needed.
