Is this annual poppy?

Hello,

Getting very large clumps of this and growing very quickly and almost overwhelming some other plants. Is it a poppy? It has quite a large think white tap root, a bit like a dandelion but a fair bit bigger.

Wondering if this is likely to explode next year if it it goes to seed..?

Cheers

 

It does look like a poppy to me

In my experience it’s an annual. Remove the flower heads when they go over and then they won’t produce seeds.

Yes, P. somniferum. Some are double, some are single, and they come in different colours as well - pink and plummy purple as well as red. You won't know which you've got until it flowers.
