"...One of the strangest plants of the desert, the night-blooming Cereus is a member of the Cactus Family that resembles nothing more than a dead bush most of the year. It is rarely seen in the wild because of its inconspicuousness. But for one midsummer's night each year, its exqusitely scented flower opens as night falls, then closes forever with the first rays of the morning sun..."

Last night was the night of blooming! Hundreds of people walked the grounds of Tohono Chul Park with flashlights searching for the Queen. The air was filled with the sweet fragrance of the the 100+ blooms.
What a 4th of July!
