Macro of blossoms from a cluster of a cactus species unknown to me. It's delicate petals show a gradient of colors from pale yellow to orange. The leaves on the lower stem (not seen here) are pale green, fat and rubbery--a stark contrast to the flowers. It blooms every year in the summer.

The original photo was worked on in Studio Artist and PS to enhance color and give the flowers a softly embossed and waxy texture.
