Stalking the Wiley Desert Asclepias

​     Spending a few days in the Sonoran Desert in Arizona was exciting for a plant nerd.  I never imagined there are so many different cacti. They are everywhere, even in the old gold mining town next to Superstition Mountain.  Of course, there in the desert, an old friend genus, the Asclepias (milkweed) was present, reminding me of our native plants in Minnesota.
