Are you getting all the root out?
Basically you don't (for almost any poppy apart from Himalayan - keeping
*them* alive in the UK for any length of time is a challenge).
Almost all poppy seeds can sit in the ground dormant for years and only
break dormancy when they see light because the soil has been disturbed.
Then you get a flush of poppies, lots of seed and the cycle begins again.
You can minimise it by dead heading and/or persecuting the seedlings
with a hoe whilst still small. FWIW I find foxglove marginally more
invasive on the seedling production front but since they only flower in
the second year it is easy enough to pull them up.
