Flower worth? If your answer is anywhere near six pounds and 29 pence, then you'd be correct. As confirmed to Eurogamer, that's the price which British players should expect to pay on February 12 (the worldwide release date).
Moreover, a SCEE representative has confirmed to Joystiq that the rest of Europe will get this unique and relaxing PSN title for €7.99. Americans need not worry about pricing, as we already know it's coming our way for $9.99.
