Poppy centers remind me of the Queen of England's crown. The crown with crushed velvet under the ( I assume gold) metal bands encrusted with jewels that meet in the centre... There are a few blue sapphires tossed into the crown gem mix, which is the blue colour at the centre of some poppy varieties, like this one... so add that into the organic/botanical design of the crown and you can see why my brain connects the two.
Poppies are gorgeous flowers, especially the orange ones... When they come with the sapphire blue around the seed pod 'crown', they are very special... like a blue jewel.
