I have no idea how long it should take your seeds to germinate. Anything yet? Keep us posted on how they do-- I have been wanting to scatter some wildflower seeds, but have been leary of doing that as some wildflowers are poisonous to livestock. I don't recognize any of the species in your mix as being noxious, but I don't have my list handy right now. Most of them sound like they would do very well. My sister has great luck with gaillardia and Mexican Hat.

Most wildflowers are slow to germinate, and it takes a certain mix of cold temperatures and winter rains for some of them.

Scatter them (in unenriched soil) in the fall, water periodically and see what happens. I scatter alyssum with them, because it's a fast germinator and gives me quick satisfaciton.

Thanks for your follow ups! I am getting a bit of growth from the seed (areas closest to the tree trunk), but don't think I'll get much in the way of blooms this year. The growth is only an inch or so high, but several varieties are evident. So, I guess it gives me something to look forward to next spring!

With the watering you're doing, you should get some California poppies pretty soon. They look like carrots, only the leaves are lighter green. In fact I guess they are related to carrots. They should flower this year, but they will only be annual for you. But then again they often reseed. Many wildflowers like a gravel mulch, and will grow and reseed better with it. For me, California poppies, Gaillardia, Mexican hat, and Prairie winecups (Callirihoe or something like that) all reseed almost to the point of being pests. Another good source for seeds down there is Plants of the Southwest.
