It's a pattern in the book "Traditions With A Twist" by Blanche Young.
It's a great book, with many worthwhile patterns in it.

There are many used copies out there. It's an older book, but still one of the better sellers.
If you do an image search on Bloomin (or Blooming) 9 Patch on Google, you'll see a lovely collection.
