Just as the title says, dayblooms are not generating mana. Right-clicking it with Wand of the Forest in Function Mode shows me that the bar is empty. I tried it with and without a mana spreader and mana pool nearby.

One thing to note, though, is that I'm playing with /gamerule doDaylightCycle false, and time is set to noon. Does that have any effect on the Dayblooms? I'm pretty sure they should still be generating mana as it's noon.
