A blue rose

I purchased the rose “blue for you” last year as I was intrigued by the colour advertised. This rose is one of a few varieties of genetically engineered roses to produce delphidin – the compound that imparts blue colour to violets and other blue flowers. Finally spring arrived and the rose has flowered. It is not strictly blue but more a lavender/purple but is the closest I have seen any rose come to the as yet impossible “blue” colour.
