Ornithogalum failure to break dormancy (and people asking to unsubscribe)

I have had similar experience with Albuca and Ornithogalum. Moving up to
northern California where summers are cool (60's-70's) from the central
valley where summer temperatures routinely get into the upper 90's-low
100's, I have noticed exactly what you say, that bulbs do not properly
break dormancy come fall. Masses of healthy roots emerge, but no foliage
nor flowers. This was never the case when they were subjected to strong
heat and desiccating conditions. It seems the key may be not just complete
lack of water but also HIGH temperatures.

Curious to hear if others have similar experiences.
