That sounds adorable!  LOL.  Can a baby plant be adorable?  I guess to me
they can.  I've raised barrel cactus (and opuntia) from seeds before.  I
never thought to study them so carefully.

Lately I've been acquiring Manfreda-like things from the PBS BX and I'm
amazed how long they wear their seed coats.  I've even tried tugging them
off, without success.  Now that I know they're berets, I'll be happy to let
them continue wearing them.  LOL.
