Gardeners' Notes:

I have had good experiences with this plant and wouldn't be without it. By snipping off the seed pods as they form I get no volunteer seedlings and have flowers until July or so. I'm in zone 6B

I like this flowering plant but as others mentioned, it does self-sow almost too easily. Still, I find it not that hard to control by ripping out any new plants that come up in spring. I also trim the seed heads before they're fully ripe to prevent new plants growing where I don't want them.

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.

Self seeds in woodlands and rocky areas in Western England, Wales and Western France. It's a lovely shade of yellow in most cases, but I have seen orange ones.
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.

Positive anelson77 On May 11, 2009, anelson77 from Seattle, WA wrote:

These grow in sun to deep shade and reseed heavily. The seedlings do pop up all over, but are easy to pull. It looks good most of the year, with pretty blue green foliage. It really lights up the shade in spring and early summer.

Positive howards On May 21, 2007, howards from Beaverton, OR wrote:

I just love its golden orange or yellow flowers. I don't mind the self-seeding at all; if self-seeding isn't desired, it can be controlled with deadheading in my zone 8b climate.

Neutral SoTired On Nov 4, 2005, SoTired from Peck, ID (Zone 6b) wrote:

This plant blooms in the tough Southeast Alaska climate (very cool summers and lots of rain) from spring until fall. It grows here in full sun to shade. It reseeds like crazy, so be sure you want it. For a semi-wild spot, where you want color all season with no fuss, it works great.

The Welsh poppy soon becomes a weed as it seeds freely and pops up everywhere. I am trying to eliminate it from some areas of my garden now.

The Welsh Poppy can be frequently found in the shady, moist hedgebanks of Devon where the summers are often cool and moist. Best to keep it out of your garden here (unless you have a wild garden) because it can be hard to get rid off. It seeds itself and regrows from its fleshy roots if you hoe its top off.

This is a very successful plant (12+ years) in my Zone 8 yard in Olympia WA (about 70 miles south of Seattle). Blooms from early spring through the first hard frosts. 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.
