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.

Back when I was in my 20's, I did a time-lapse study of a cactus seedling
breaking ground. The seedling was way too small to get the camera close,
so I
placed a prism adjacent to the erupting seedling and shot vertically
downward at
the prism. I set the camera on a ring stand and took one or two shots a
day. Barrel cactus seedlings are very amusing -- nearly spherical with
markings
that make it look like a face, the two cotyledons on top are like tiny
cat's
ears, one of which wears the seed coat, like a beret. That was many years
ago,
and the film is lost, alas.
