Only on display at Longwood Gardens in Kennett Square, Pennsylvania for two to three weeks, the Himalayan Blue Poppies are stunners and considered a rare garden treasure. Almost extinct in their native habitat of Bhutan, photographers flock to Longwood to capture some photos of these amazingly true blue spectacles. Sporting deep sky blue crepey petals with mauve highlights and a ring of golden stamens and anthers, the plant is much sought after to add to gardens.
Unfortunately, in North America it can only be grown in Alaska, the Pacific Northwest, and parts of New England successfully. Meconopsis grandis is the national flower of Bhutan, a country high up in the Himalayas, above 10,000 feet, and wants cool, cool temperatures, like 45 to 50 degrees F. The conservatory at Longwood Gardens is certainly warmer than this so the flower is fleeting in its beauty.
Once considered a myth and brought back to the west by plant hunters, the Blue Poppy is a challenge to grow for the most experienced gardeners and a mark of distinction for any gardener succeeding in its cultivation.
Requiring moist and cool conditions, Longwood Gardens, one of the few places to see them, forces the variety Meconopsis ‘Lingholm’ into bloom every March and increases their number each year because of their popularity.
Drawing large numbers of people, especially photographers getting that perfect shot, the colors are unbelievable-saturated blues with streaks of mauve plum tones- on a large 4-5 inch flower.
A shade of blue rarely seen in other flowers, the foliage is also stunning with grass-green hairy stems and leaves. Longwood Gardens gets their Blue Poppy plants shipped to them from an Alaska grower in the fall and they grow them in perfectly controlled greenhouse conditions to force them into bloom for display in the spring. Longwood has two different batches that it refreshes the flowers with so they can extend the brief bloom time for visitors.
Growing in the warm clime of the conservatory, the mauve highlights were evidence as a sign of stress. The ephemeral quality of their blooms is part of their attraction and charm and visitors flock to see them.
Demanding a rich loamy well draining soil in partial sun in cool conditions is the primary ingredient to successfully growing this garden gem. Way too hot in my mid-Atlantic climate, I get to photograph them and enjoy them at Longwood Gardens in the spring.
