A couple days ago, walking back to the office from the deli I got a
photo of poppies that turned out pretty well. By shooting in a direction
that shade was in the background, I ended up with golden poppies against
a black background.
My first thought was to take one my plastic tubs, paint the inside flat
black and if I want to photograph flowers, put that behind the flower so
that I can get the instant dark background.
Upon reflection, I thought that what would be better would something
like one of those "pop up" light tents:

but made out of an opaque black fabric. I suppose I could do something
similar with the light tent and opaque fabric over it, but I figured I'd
ask if anyone knows of such a "porta-cave" already on the market.
Not sure what the question really is here. Are you looking to shoot
flowers on a black background in your house?
You know that you really just need for your subject to be a few stops
brighter than your background (about 4.5 I think) and your background
will be black. You can shoot your flowers using flash on a table where
the "background" is through a doorway into a dark hallway or similar and
you'll get the effect of a completely black background. This is
especially true if you keep a smallish aperture, like f5.6-f8.
I suspect you'll get no satisfaction from your "dark tent". If you
setup a flat black painted surface anywhere near your subject and any of
your light spills onto it, your background will show up as some shade of
grey.
