Gloucestershire Solitaire is a variation of Flower Garden Solitaire using two packs. The Foundations when complete wrap from Ace to King twice. This is the primary difference with Flower Garden. Along with the layout!
There are two Reserve Piles with 26 Cards in each. I would imagine that these piles could be called the Bouquet as Gloucestershire Solitaire is a derivative of Flower Garden.
Any of the cards in the 'Bouquet' can be played to the Tableau or Foundation.
Some versions use one Reserve pile. Two fitted better on the screen size that I am using when I play:)
This is one of the games where it might be worth using full-screen depending on your monitor size.
