This storied gardener tells of lollipop skies in a country that is
neither here nor there, and is pinpointless.

Author's initials are C.S.

You might want to keep an eye on this forum thread where people are
discussing the stumper in question:

C.S Lewis - The Chronicles of Narnia?

Not sure if his stories tell of said stuff, but he does right fantasy!

I thought CS Lewis at first also, but couldn't quite figure in the
rest of the stuff.  The country that is neither here nor there could
fit.  The pinpointless reference could be worked in as follows -
Pinpoint is a description of a kind of shirt, which could be found in
a wardrobe.  In CS Lewis work, The Lion, the Witch and the Wardrobe,
the Wardrobe is the entrance to the magical world, so that the
wardrobe contains the country rather than Pinpoints (I know, a bit of
a stretch).  I couldn't confirm Lewis as a gardener however, but it is
certainly possible.

Another possibility is Craig Shaw Gardner.  He is a storied (i.e.
writes stories) gardener (Gardner), who writes fantasy, including some
that is somewhat cartoonish/humorous and set in a world that is
neither here nor there and could include lollipop skies.  I'm not
familiar enough with his works to say if they do for sure, but they
sound like they could.  That whole pinpointless thing throws me
though.

I think you are on the right track with CS Gardner i just need to know
where to look and what books would have the reference in it

'Pinpointless' seems like a strange word to use, so maybe it's a clue?
To pin-point something means to find it, so pinpointless doesn't even
make sense - it would need to be un-pinpointable to mean 'unfindable'.
Curiouser and curiouser...

I don't have it all figured out quite yet, but I have made a couple of
ties between this riddle and a collection of childrens stories called
"Rootabaga Stories" written by Carl Sandburg.

Does it happen to be a poet by the name of Carl Sandburg? His poem,
"Dream Girl" mentions something along those lines.
