Okay, Okay....I thought of that fire thing because I had a grill fire about 10 years ago. I had a grill house it was a semi covered structure and I put sedum around it and some bushes to make it look pretty.
The fire went up and my friend grabbed a rake and pushed the grill into my sedum bed. I was screaming get them off my plants, he was yelling what plants what about the roof.
He was concerned about the roof on fire. I was worried about the sedum on fire.
Those sedum did not blink.
