Actually, this flower is called Bouncingbet or Soapwort. Found these on the banks of the North Saint Vrain Creek in the Button Dam Preserve.
These 4 inch high Alpine Sunflowers follow the sun, turning their heads in a full circle on sunny days.
Every year I make a special trip to see the Plains Prickly Pear cactus on the Twin Owls Loop. I just think it is cool that these very ugly rough plants develop such amazing flowers. Look in the hottest, sunniest spots you can find.
The American Alpine Speedwell is a tiny flower, about 6 inches tall with a cluster of tiny blossoms in a 1/2″ group at the top. I used my Ollo Clip magnifying glass to try to get a close up so that you get an idea of the intricate little petals.
Compare the Parry Lousewort and the Bracted Lousewort (two last pics). They differ slightly in size and the shape of the flower beak, and in the stems and leaves. Normal people would likely think they are the same flower, but they look very different to me!
I’m pretty sure this one is Woundwort — another really unattractive name for a perfectly lovely flower. This grows near streams in wet mud.
