Cowboy's delight (Sphaeralcea coccinea) is starting to bloom on the south side of Harriman Lake. False dandelion (Agoseris glauca) seems to have popped up overnight and everywhere.  Shepherd's purse (Capsella bursa-pastoris) is now showing its heart-shaped siliques nicely. And, we noticed bulbous bluegrass (Poa bulbosa) along an irrigation ditch this morning,.

We went to the Green Mountain dog park this morning. Several new bloomers were out. Drummond milkvetch (Astragalus drummondii), Short's milkvetch (Astragalus shortianus), Leafy wildparsley (Musineon divaricatum), and Jim Hill mustard (Sisymbrium altissimum). The Jim Hill mustard is about the same size as, but has much coarser leaflets than the tansy mustard that was featured last week. Drummond milkvetch is an early favorite. It's a hairy plant, and combined with the creamy, white flowers, is easy to field identify.

The dogs and I saw wintercress (Barbarea orthoceras) blooming in the ditch on the south side of Harriman Lake today. I can't get the picture rotated 1/4 turn counterclockwise, but here it is anyway.
