Talk:The Crimson

I'm seeing some red mossy stuff growing on regular stone in my world, but nowhere near the actual crimson locations. Does the crimson spread on stone in easy mode or is this something unrelated?
 * Probably unrelated, red moss our some such. If it were spreading crimson there would be Crimstone instead of regular stone

According to the wiki, it says crimson is halted by sunflowers, I planted sunflowers around my central biome, and all that did was end up with the crimson smashing the sunflowers into pickupable items and spreading anyway. Is this a bug, or is the information regarding it being halted just completely misleading?
