Western groundsel (Senecio integerrimus), blooming in the prairie among Woods rose.

I have been able to start the groundsel from seed, but one plant that has been more difficult is Douglas' brodiaea, or wild hyacinth (Triteleia grandiflora). They are pretty persistent and fairly common around here, surviving even when every other native has been eliminated, but I have never gotten the seeds to produce plants. And that's when I can find seeds, as some animal finds them delectable and generally the seeds are gone before they are mature. Fortunately there has been quite a bit of it hanging on in the southern fence row, and over the years I have encouraged it to move north. It grows very slowly, putting out a green hair at first that gets thicker over the years until at last it puts up a spectacular flower. The deer chomp these too, but this year there are enough that some have escaped being chomped. Here is one in full bloom that I found today.
