I was commissioned to design a garden about 3 years ago as part of a new build house.  The project was delayed when the client became ill but is now back on track and our first meeting about landscaping was today.  

I specified some really great polished black granite containers 60x60cm cubes.  Today I find that these are now discontinued.  Can ny one think of a suitable alternative, I already looked at Iota and Cadix.  They are to go along side a black reflection pool.  (Oh and yes I know black is a really bad colour for a container as the plants can overheat)  I have used the black granite before and the way they reflect things is the key factor.
