The question was more one of where it gets the resources to grow like that. My bad for wording it incorrectly. I've asked it before but normally it gets buried under the avalanche of people with problems about Victoire.

Are the beds essentially giant mana vacuums that draw in the surrounding ambient magical energy or is it more of a biological thing?

Edit: Gaaaaaaaash dan it BC. I'm trying to go for non-hostile learning here.

So that was the question, huh? The answer is simple. They are plants, magical undead plants, in fact. Plants grow as long as there's space for them to grow. The roses never ever used magic power to grow.

They used to require blood and, in fact, still do.

The blood to power them comes from the armies that everyone ignores. As said in the very first battle of the RP, Victoire usually sacrifices lesser demons to kick start her roses and, after that, anyone who who dies powers than up.

People keep forgetting about the mooks, I just don't see why this was ever an issue. In places where there's native life, like Arcadia, , anything in their path bites the bullet too.
