Asclepius (milkweed family) growing near the house: butterfly weed (Asclepius tuberosa spp. terminalis) and antelope horns (Asclepius asperula).
I had to look up the botanical names, being normally happy just to remember the genus.
Its name comes from Asklepios, son of Apollo and god of medicine.
Antelope horns is definitely an odd-looking wildflower, with its green-turning-white petals.
Butterfly weed is a mainstay of high-altitude xeriscape gardening, but this one is wild. Monarch butterfly caterpillars feed on antelope horns in some areas.
