Can you name the cactus from the bloom?

How about if I show you the cactus?


The blue stems are the giveaway. So ignore that photo. Pretend you never saw it. Focus on the bloom above.

Is there a prize for getting it right? Yes! And not just the satisfaction of a job well done. There’s also recognition from your peers. And a Lithops, to be shipped anywhere in the US except Alaska or Hawaii. Sorry for the restrictions.

Is there a clue, too? Sure! It’s not hardy in Berkeley.
