Quick answer
If your Escobaria Vivipara has sunburn, the most likely cause is: Escobaria vivipara (syn. Coryphantha vivipara, beehive cactus) is easily sunburned when dormant or half-dormant tissue is exposed to strong sun while still frozen, and is especially prone to scorch on the variety varicolor when sudden autumn freezes follow warm exposure. The author of the source book reports varicolor has suffered from sunburn during sudden autumn freezes in his garden.

- 2. Plant Escobaria vivipara on the north or west side of a large rock that shades it in winter while still allowing overhead spring sun once tissues have thawed, so morning sun does not hit frozen stems.
