they showed up on my lot as a gift from God .. one of the few things that were truly a gift ... and not a scourge.... lol

you will recall .... i used to roundup my hosta beds .. so it never became a problem.. nor was it aggressive ...

luckily it had rather unique leaves so i could spot them and avoid spraying most of the few i had ... actually i had to look them up.. because i thought they were annuals ... go figure on that ..

like all poppies.. they just made me happy ... especially because they were a yellow poppy.. who knew.. lol ..

I had these years ago and remember really loving them, but they disappeared. Kinda forgot about them until you mentioned them lol. Could easily have been from my neglect/ignorance that they petered out, as I had them when I was a new gardener (my knowledge has increased since then, but can't say the same for my attentiveness to the garden lol!)

Sorry I can't be of more help!

I’ve had a few clumps over many many years. Shade, average moisture. They can seed down and spread some if happy.... but are very easy to control by yanking any out that you don’t want or just cutting off the seed pods that hang out for a long time. Great plant

Ok, then -- sounds like it may be a winner! Will put it on my list for 2021. Should be able to source it locally (well, hopefully...)

mxk, I just happened to be looking for certain seeds and came across celadine poppy seeds on Prairie Moon Nursery. The notes do say it may be hard to germinate, and I don't know if you even want to try growing this from seed, but when I saw it I thought of this thread and thought I'd pass it along

My sister had a ton of them in her garden (zone 5a/b Canada) and they bloomed at the same time as her bleeding hearts (June?). They looked beautiful. They were in a fairly shady location (along with Solomon’s Seal)

Thanks, Dee!

I grow mine in my wooded area with part shade, Usually blooms in May for me in my zone 6.Reseeds nicely.

I’ve got a couple, in part shade and part sun, avg moisture, that have come back for a few years. We’ll see whether they survived last summer’s drought. I’m z6.

mxk3, it is such a pretty spring plant. You cant go wrong with it. (Do a search in this forum....lots of good threads).

Ooh Ooh Ooh! Stumbled upon some nice potted specimens when I was at the nursery this evening. Of course they came home with me!

They're doing well. Two are in a bit drier locations and the foliage doesn't look quite as fresh as the one in a shadier, moister location but still look pretty good. I just noticed the seedpods last week -- they're cute!

I thought the seedpods were very cute too. The European version reseeded too much for me and it took quite awhile to get them out. I hope they're all gone because they look so much alike, but the seedpods definitely distinguish between the two. I hope the native reseeds as well as the non native did. Glad they are doing well!

I'm familiar enough with both and I think you can tell the difference pretty easily. The non-native (lesser celandine)'s lobed leaves are smaller and have smaller lobes. If you can't tell when the seedling first comes up just wait a few days. You can certainly tell the difference when its about to bloom. Lesser celandine is easy to pull up. Its sap will stain your hands and clothing.

I bought mine at a neighbor's plant sale years ago..I've had very few (3?4?) seedlings..I expected more spread but I think what I read was talking about the European invasive species and I didn't know the difference..I'm glad I have the native wood poppy..I'm in the process now of removing the lamium..the poppies and hostas will be prettier without the lamium..the "surprise/magic/ resurrection" lillies in back of the poppies aren't a problem..

Good to know that it doesn't reseed as well. I did buy a plant at a yard sale and it didn't produce any seedlngs the next year, so I bought 3 bare root poppies this spring which are all growing. Maybe I could collect the seed and start more that way too.
