Cylindric Blazing Star problems — and how to fix them
Cylindric Blazing Star (Liatris cylindracea) 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.
Corm rot in wet soils
The most common failure mode. Heavy or poorly drained soil causes corm rot, especially in wet winters. Plant only in sharply drained substrates; add grit if needed.
Sparse flowering
Plants in too much shade or overly fertile soil produce leaves but few flowers. Move to full sun and avoid feeding. Competition from aggressive grasses can also suppress flowering.
Leaf rust
Orange pustules on foliage caused by Coleosporium liatridis. Remove affected leaves and improve air circulation. Serious infections are uncommon in well-sited plants.
