Lachenalia sargeantii

Even though some bulbs for whatever reason refuse to come up, they don't
seem phased by a continuous supply of water throughout the winter. The
problem with these things is the offsets are so small and soil-colored,
they are very easy to miss when being checked on. I would just water it as
usual and forget about it until they do decide to emerge (if you have the
space and patience that is).

In terms of the lamb, you might want to save an offering to the gods for
keeping Cyrtanthus spiralis alive or setting seed on Worsleya, but it might
not hurt when trying to get L. sargeantii to bloom. Sarcasm aside, no
sacrificial rituals are necessary to grow this species.
