This is a dangerous plant and im surprise that they sell them. I will be more careful in the future. I have a 5 year old grandson thats always with me on weekend and would die if anything happen to him. Shame on those plant place.I have burned it. Thanks for letting me know so prompley about the plant.
I agree with Resin's ID and also that it's a "beauty". I'm very partial to poppies personally and just want to make a suggestion here. If you are into growing from seed, let a pod ripen and save the seeds to direct plant next year. Try dead-heading the rest or you could end up with hundreds of volunteers in your flower beds. Even though they are easy to pull out, it could be a pain and they do not transplant well. Your Papaver is most likely a cultivar, so its progeny could end up being different colours or possible even some singles.
I don't allow my 3 year old granddaughter in the garden unsupervised, and although she is long past the stage of putting random objects in her mouth I suppose any child could take a bite out of any plant at any time. They are likely to encounter significantly more toxic plants than this one and should not be eating any plant without the direction of an adult.
Betty, if you are interested in trading seeds for ones collected from a different color, d-mail me.
