South African succulent Euphorbia. Probably the most common of the medusoid Euphorbias in cultivation. Like the other ones, it grows a central "head" with many "arms" (the venomous snakes of Greek mythology) radiating outward around it. The stem may grow a few inches high and wide, the total width of the plant up to a foot or more in strong light. Not a great choice for low light situations (the arms grow weak and long, sprawling all over). Yellow flowers. May be self fertile. Easy to grow from offsets or from seed. May blush red in direct sun. Extremely photogenic when grown right.

Don't be afraid to attempt to rehabilitate a Medusa's Head even when it looks bad. Many times the plants have been over-watered and can be salvaged with a little TLC. Always check for root mealies by removing the plant from the pot. Replace the old soil with fresh soil.
