White-Budded Sundew (Drosera leucoblasta) 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.

Caused by standing water pooling in the rosette centre or excessive heat. Improve air circulation, keep water in the tray rather than overhead, and ensure temperatures stay below 32°C during summer.
Failure to produce gemmae
