I used to know it LOL!

It's a Sisyrinchium of some sort, probably either White-eyed Grass (Sisyrinchium albidum) or Prairie Blue-eyed Grass (Sisyrinchium campestre)

Prairie Blue-eyed Grass (Sisyrinchium campestre)

White-eyed Grass (Sisyrinchium albidum)

Sisyrinchium atlanticum I think ..

The photos of "eastern blue-eyed grass" in the US look more blue, the one you have matches those in Japan and Taiwan.

Thank you both very much for your help.

flaflwrgrl has pics just like mine under Prairie Blue-eyed Grass (Sisyrinchium campestre) she also has many other pics under other Sisyrinchiums... I'll shoot her an email to see if she can give her imput here.

The flowers themselves aren't going to be that helpful in figuring out which species it is. With the exception of a couple of West Coast species, all the North American Sisyrinchiums have basically similar flowers (some species have a higher proportion of individuals with blue flowers, some have a higher proportion of individuals with white flowers, but all are capable of producing white, blue, or bicolored flowers. S. campestre and S. albidum have 1 to 2 sessile inflorescences per stem while S. atlanticum has 1 to 4 stalked inflorescences per stem. Can't really tell from the pictures whether the inflorescences are sessile or stalked, but there doesn't appear to be more than one inflorescence per stem which leans towards S. campestre or S. albidum. S. campestre and S. albidum or not easy to tell apart. S. albidum USUALLY has two inflorescences at the tip of each stem with three bracts below them. S. campestre USUALLY has just one inflorescence at the tip of each stem with two bracts below it. Usually is the key word there.

Sisyrinchium campestre:

The plant can be identified by the single inflorescence at the end of each stem, the two, and the only two, bracts subtending the inflorescence, and it's winged aerial stems.

Another species, S. albidum, is similar but has typically two inflorescences at the end of each stem. The flowers of this species can be white or blue but are typically white.

Sisyrinchium atlanticum:

Sisyrinchium atlanticum is somewhat similar to the more common Sisyrinchium angustifolium, but can be distinguished by the following characters: S. atlanticum - stems and leaves glaucous, stems slender and narrowly winged, peduncles slender; S. angustifolium - stems and leaves green, stems and peduncles broadly winged.

Sisyrinchium angustifolium:

The numerous, narrow, light-green leaves of this perennial form dense, tufted clumps which steadily grow with new foliage during the season. The flattened, leaf-like flowering stems may be up to 18 in. long and bear light-blue, star-shaped flowers a few inches above the leaves. Height is 1-1 1/2 ft. Several delicate, blue or deep blue-violet flowers with yellow centers in 2 broad bracts top a flat stem, generally only 1 flower at a time in bloom; stems taller than the clusters of narrow, sword-shaped leaves near base.

Have fun Christine! Now all you need to do is decipher all those technical terms, get specimens and come to an informed conclusion.

There's some botanical drawings on this site ..

Thanks Janet! Lol! It sure seems like I always find the kind of wildflowers that I think will be easy to identify but turn out like this!

thank you Jay and Kent.

I sure hope I can find the plant again! haha I ran across it on a walk with the dogs and its a job just to get a pic without all of their noses in the way!
