Looks great! I see some hedgehogs, and chanterelles, is that amethyst deceiver on the right?

I have! I had success with bulk poppy seeds from a bakery. I have heard of people using grocery store seeds. You'll want to make sure they're fresh seeds/haven't been sitting in the pantry for years. Depending on where you live, it's best to sow them right before the last frost. What I do to recreate this is to put the poppy seeds in freeze for at least 24 hours before I sow the seeds.
