Several species popularly known as winecup or poppy mallow bloom in Texas. In my area, the Purple Poppy Mallow (Callirhoe involucrata) spreads along the ground, forming low, dense mats across prairies, fields, and roadsides. Its deep magenta, cup-shaped flowers are common from mid-spring to fall.
The closely-related Tall Poppy Mallow (Callirhoe leiocarpa), a spindly, erect plant of the hill country that often reaches a height of two to three feet, produces single blooms atop long, leafless stems like the one shown above. Its dark purplish-red to wine colored flowers close each evening, and remain permanently shut after pollination.
When I found a few Tall Poppy Mallows re-opening on the morning of April 5 outside Cost, Texas, one held a surprise. The small flower, less than an inch across, held an even smaller sleeping bee that had checked into the Winecup Hotel for the night. As I looked into the tiny cup, the bee awoke and stirred, then peered over the edge of the petals. Perhaps it was hoping for room service.
