i think i speak for the great majority of gardeners when i say that we are constantly looking for blue flowers. Real clear blue - not purple, not bluish purple, not violet - BLUE. Unfortunately, there aren't many fitting that classification!
Grape Hyacinths(Muscari "Valerie Finnis ")
When you read many plant catalogs, they will describe ALL the Grape Hyacinths as a "Clear Blue!" color, but i don't understand it - they are very definitely PURPLE! Just like in the photo below (and even looking all over the 'net for this picture, almost all varieties were shown - as blue). Valerie Finnis is the only one i've found that REALLY is blue.
There are two blue flowered plants i have not yet succeeded with - one is the Himalayan Blue Poppy (Meconopsis), which really wants the cool, moist summers of the Pacific Northwest, and the Corydalis 'Blue Panda', also another one that doesn't like our hot summers - but I'll keep trying!
Glory of The Snow (Chionodoxa )
The first blue of the year (actually, the Scilla {below} blooms when the Crocus bloom, but the flowers are so tiny and delicate that it's easy to nearly overlook them)
The tiny stripes on the above blossoms are a subdued baby blue
Pulmonaria (I think it's "Blue Ensign" - unfortunately, i lost the tag) blooming right now - even though the buds are pink, the open flowers are EXTREMELY blue!
...And one more.... the pretty blue forget me not-like flowers of the Brunneras....
