You can see where it gets its name from! The center of the flower looks like a lifesaver. This is a easy to grow succulent.
Light: part sun, if grown indoors place in a bright window. When grown outside they prefer to be in the shade.

soil: well draining cacti and succulent soil
Fertilize: monthly with a fertilizer for cacti and succulents
Hardiness Zone: 10
you will get a plant in a 4” pot. If in bloom, I can’t promise that the flowers will stay intact during shipping.
