Flowers of Boyce Thompson Arboretum

Honey Bee arrives for. . . dinner?  It doesn't realize but will certainly enter as a 2nd or 3rd party into an orgy of cactus fertilization.  Usually there are several that take part.
Open petals are sexy for bees and insects.  Bees have an easy time...among humans sex is selective, between flowers and bees, sex is indiscriminate.  .
Showered by fallen Paloverde blossoms this Hedgehog Cactus stands out.  It says, "Hey, look at me!!"  The Paloverde blossoms have had their chance.
Either a beaver tail cactus or what Boyce Thompson Arboretum calls a "red prickly pear cactus flower" it stands out like a stop light in the desert traffic.
One of the common yellow blossoms of the prickly pear.
The yellow/red is a common variation within the prickly pear family.  The prickly pear is notoriously "promiscuous", allowing pollen from a variety of related and unrelated species.
One of the Boyce Thompson "variants" from its "Cactus Garden."
