Absolute Treasure is one of my favorites and this year I added Ice Capades, another light blue. I have tried for several years to get some really blue irises but a lot of them that are described as blue are really a shade of lavender/blue. I also added Fantastic Blue and Blue Satin Ruffles and I hope to see them bloom this spring. I saw a photo of Ty Blue and thought it was blue and white. I planted it last year and although it is a lovely big bloom, very light with very dark beards and horns it is not a true blue.
