poppies

I went outside this morning (before the drizzle started) and saw that the poppies have opened.  What started from a single red california poppy left over from the previous residents has now grown into two small areas full of them.  (One of those areas was unintentional.  The seeds looked just like the strawberry-spinach, so I threw down a lot of them this year.  Oops.)

I see that I have both pink and red.  How is it that they end up looking square?



I don't suppose anyone would know what this plant is?  I dug it up this morning because of the crowding, but I might rescue some seeds if it has an interesting story to it.



The flowers look almost vicious.
