Up to the DM really.

That's at least CR 16.
Why's that? If you kill them before they explode they don't come back, and most 13th level characters should be able to finish this off within 10 rounds (never known a fight to even go that long).

Edit: Actually, why haven't these over-run the plane of fire yet?
Cuz it's infinite. Also, until they find a fire-based creature they only reproduce 1 of themselves. So basically all they are doing is moving along as the same plant.

also, your avatar, is that from 'the village'?
