PlantFiles: Alfilaria, Red-stemmed Filaree, Pin Clover, Pin Grass, Wild Musk
Erodium cicutarium

I am not currently growing this plant, but I have gathered a large number of seeds for it. I plan to grow it in the future. Here is info I have on its edibility.

"Edible Wild Plants of Eastern North America" by Fernald & Kinsey has this to say about Alfilaria, also known as Storksbill:

"The Storksbill is an occasional weed around towns and especially in the neighborhood of woolen-mills, whence its seeds have been brought from the Southwest entangled in wool. The plant is extensively naturalized in the southwestern states and several writers say that the young foliage is eaten raw or cooked by the Indians. In our Southwest it is raised as an important winter-forage under the name Alfileria."

"Edible Wild Plants: A North American Field Guide" by Elias & Dykeman has this to say:

"Harvest: Gather young, overwintered leaves in early spring when other wild foods are scarce. Be certain leafstalks are hairy.

Preparation: Chop leaves for salad with other greens. Boil leaves in lightly salted water until tender, about 10 - 20 minutes. Serve with butter, lemon juice, and herbs.

Poisonous look-alikes: Leaves resemble those of the parsley family including Poison Hemlock. Picking only hairy-stemmed leaves very early in spring should help you avoid errors. Be sure of identification!"

one of the most common ground cover plants in the Great American Desert, I have been delighting in its tiny blooms for many years now and was pleased to find that the most numerous ground cover on my recently purchased land was in fact this pretty plant

This plant is also called Heron bill Filaree. It is native to the U.S. It produces blooms profusely for many weeks in the spring. The finely divided, fern-like leaves and deep roots have a strong pungent smell.
