There is a block called Squash blossom that looks a lot like that but not exact. Here is a link to google images. I am sure you can find a pattern for it. I believe Quilters Cache has one.

Edited to add I found quilters cache but it is a large block.

Additionally you could modify the block "Delectable Mountains" to get that look as well.
