So . . . I'm standing in line at Lowe's just now having saved one of these red succulent beauties from a certain death by overwatering in the shade: http://davesgarden.com/guides/pf/go/1930/ It was on the distressed rack for $3!

Back to the check out line. There was a display of "Cosmic Cactus." They are short, round leaved things with neon colored spines. The display was a mess, they were dropping everywhere; so I helped them clean it up a little and I guess a few fallen leaves stuck to my hand (see photo). What do you think? Cool or disturbingly unnatural?
How long before I should try to stick them in cactus mix?
