Variable-Leaved Butterwort problems — and how to fix them
Variable-Leaved Butterwort (Pinguicula heterophylla) 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.
Bulb rot during winter dormancy
Any moisture reaching the dormant bulb — even high ambient humidity — can cause rapid rot. Remove from the tray immediately when leaves begin to die back, store in a dry spot, and do not water at all until new leaf tips emerge in spring.
Tall leaf collapse
The unusually upright, narrow leaves become unstable in low light or if the plant is moved while in full leaf. Provide consistent bright light from above (not the side) and stake very gently with a thin cane if leaves consistently flop. Avoid repositioning the plant mid-season.
