That's prairie, with two I's. If you missed my note back here and also on the state flower info page explaining errata (scroll down to the bottom of the page), take note that the pattern you may have for this block might need to be corrected to include the missing I. In addition, as I went through all the blocks (again) checking spelling and such, I discovered another blunder--the block for Oklahoma had something extra. Just how in tarnation 'ROSE' got in there I'll never know. It should be mistletoe, plain and simple. Fortunately it's a lot easier taking something out than it is adding something in--so simply omit it.
This is the second state claiming the ever-faithful "wild" prairie rose for its flower. The former mentioned was Iowa which has already been stitched and blogged about here. Even though it's the same flower, I did both slightly different and like them equally well. Here is an excellent photo of an actual wild prairie rose; and a host of other varieties as they hybridize naturally.
The wild prairie rose (Rosa Pratincula), also called Rosa Blanda or Arkansana, was adopted as a state flower of North Dakota in 1907. It grows in abandon along roadsides, in pastures, and in native meadows. It has five bright pink petals that fade to white in full bloom, with a cluster of yellow stamens in the center. These petals are edible, and the rosehips that follow can also be consumed in various forms, and were used in ancient times to make medicines.
