This species differs from the rest of the genus in being much more adaptable and easier to grow in the garden. It's also different in its native range (Western Europe and not the Himalayas). Molecular phylogenetic research has led to the proposal that it should be removed from the genus Meconopsis. http://www.maneyonline.com/doi/abs/10.1179/204234811X1319445...

The drawback to Welsh poppy is the very short bloom period - shorter than many other perennials. When the plants are finished blooming, I leave the leaves on the plant for a few more weeks to build up strength for next year, then cut it down to the ground.
I live in the southwest corner of BC where the weather is generally wet (except for roughly 2 months of drought mid-summer). The plant does well here & survives the dry period fine but it's finished blooming by then anyway.
Mine come in two colours - a bright lemon yellow & a medium orange. I prefer the yellow & am slowly pulling & digging all the orange flowered plants up. Since I see only one photo of an orange flower, I'll post a photo of mine that are orange.

Puts up with cooler conditions well, thrives in damp, shady areas of woodland and half way up wooded mountain sides. Would probably suit the Pacific North West, Norway, Iceland, Faroe Islands, Falkland Islands and West coast region of New Zealand well.

Nice clear yellow flower. It reseeds VERY freely in shade and semi-shade. Pest-free and somewhat drought-tolerant. We've had a gruesome summer (from a plant's viewpoint-and mine) with many 90+ degree days and no measurable rain for nearly 2.5 months. It seldom rains in the summer here anyway, but the temps are not usually so high for such a long time. A very welcome sight in early spring - it thrives on spring rain and cool temps, but also grows well in the hostile conditions described above.
