Monarch butterflies rely exclusively on milkweed plants...
for laying their eggs and feeding their caterpillars as it is the only food source they can consume. Here’s one in the riparian zone of Castle Creek.

Selenium is accumulated...
by a number of plants in sufficient amounts to be toxic, and the lemon-yellow spike-shaped blossoms of this desert beauty belie the dangerous concentration that it may contain.

Big and bright and beautiful bunches...

from opening globemallow blossoms. I’ll have to go prospecting for the entrances to their underground hives, given away by their tiny sedimentary turrets.

Yellow cryptanth (Cryptantha flava).
Bright scarlet blossoms on this claret cup cactus...
belie the extremely dry winter and early spring in the region. It’s the loveliest cactus in canyon country and you can’t change my mind.
