Persian speedwell

Yesterday, on a short walk in the park, we saw a patch of flowers neither of us recognized. Today, we went back for a longer walk, and I took my camera.

After significant hunting around (it wasn't in my Audubon guide to North American wildflowers, and the first several website I tried didn't find it), I have tentatively identified them as Veronica persica, the Persian speedwell or Birdeye speedwell. I've tossed a photo on Flickr so I can show you (I just picked one of the three I took and cropped it a bit; the color shown on my monitor is similar to what I remember, though of course your hardware may vary).





It doesn't match the Wikipedia description, but flower colors do vary, and nothing else seems to fit. If anyone (jonsinger?) has a better identification, or is confident that this isn't V. persica (even if you don't know what it is) please let me know.
