Bloom - Define what it's referring to

Entrak

Translating BZ to Norwegian and I've arrived at "Bloom"/"Bloom".

Is this in reference to the lens flare effect or to the Bloom Plankton? Or to a flower bloom?

Take a look at this:

It is the glow around the creepvine seeds, for example.

Yes, I know what bloom in term of graphic tech is, but the text to be translated does not state what it's referring to.

Context is important.
