Endrous Roots: Timed Damaging Plants (For End Update)

We have some traps, but we don't have many timed traps. Endrous Roots would spawn in the end and every few seconds it would "bloom" and damage anything standing in it. It would deal a little bit of damage, but with redstone you could change the amount of damage and/or when it causes damage. Endermen & future End Creatures could also influence the damage & timings when nearby. This would be great for adventure maps, traps, & pranks. You could also make it not do any damage by crafting it with warped roots.
