Sibthorp's Everlasting problems — and how to fix them
Sibthorp's Everlasting (Helichrysum sibthorpii) is generally low-drama, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Crown rot in winter wet
The greatest threat in cultivation; persistent moisture at the crown, especially in cold weather, causes rapid fungal collapse. Grow in an alpine house or place a pane of glass overhead in winter.
Root-knot or fungal root disease in heavy soil
Planting in clay or moisture-retentive compost leads to rapid root death. Always use a very gritty, free-draining mix and incorporate limestone chippings.
