|The Queen of the Night Peniocereus greggii or night-blooming cereus, in all her glory.
Mystery. Majesty. Beauty.
What is Bloom Night?
Each year, for one evening only, Tohono Chul
opens its doors to visitors from around the
world to experience the mystery, majesty and
beauty of the Queen of the Night, the night-blooming cereus Peniocereus greggii.
The Queen of the Night is here in abundance as
Tohono Chul is home to the nation’s largest collection.
When the summer heat begins to build, the buds of the night-blooming cereus begin to appear. After a period of start-and-stop growth, the buds blossom in a mass blooming on one night between the end of May and late July. Experience the magnificent Peniocereus greggii in its full glory; stroll luminaria illuminated trails leading to each plant; marvel at their gorgeous flowers; breathe in their intense and intoxicating scent.
