Do you know what kind of annual poppies they were? Is it the somniferum that sprouted? I'm not sure but the germination requirements for the different seeds might vary somewhat (e.g. different temps, moisture). Usually within the same family of plants the requirements are similar but some might take longer to sprout, need more or less light exposure or moisture, cold strat, etc.
So I'm confused- which sprouted and which didn't? Was one naturally dropped from the plant and the other broadcast commercial seeds? I often find that really fresh seeds (just dropped by or scattered seeds fresh from the plant) sprout much better/faster than seeds that have been stored for a while.
