The Blues in the Conservatory at Longwood Gardens, Pennsylvania, every year
Longwod Gardens, Pennsylvania, Research, Conservation and Pleasure Gardens
Legacy of Pierre S. du Pont, 1870-1954
The Spring in the conservatory at Longwood is often filled with blue flowers.
Blue, the conservatory reminds, is the rarest colour for flowers, fruit and foliage, occurring in less than 10% of the universe of such.
The Himalayan Poppy (Meconopsis ‘Lingholm’)
In the autumn, the Gardens begin the forcing of the rare blue poppy for flowering in early March.
The plant contains pigment only for blue. This may present from blue to pink depending on variables in the soil.

I also like blue flowers.
The ones you’re showing are beautiful.
This year I planted a poppy of the Hymalaia, I expect, full of hope, that it blooms.
Louis, I hope for you! I like poppies almost the best of all flowers!
I have heard that the Himalayan species may take some years to flower and when they do, they set seeds and then the plant dies. I hope that if you found a variety for sale commercially, it flowers soon and you post it and you can maintain it, if you want to!
