such interesting layered colors with their paper-like petals

my yard has the standard orange California poppies (because in CA) not sure if house owner planted them, they sort of just show up everywhere. anyway, very inspired by your yard, to expand on this idea. did not realize such range of styles

if you don't mind, I'd like to know the source of plants? wild? neighbor? local store? order online? I did read somewhere poppies need a year or 2, so I think need to start now
