Is Tohono Chul Night-Blooming Cereus Mass Bloom happening right now?

As of today, in season, building toward peak (~June 20). Earth Exhibit tracks the live conditions and flags it the moment it is on.

Each summer in the Sonoran Desert, night-blooming cereus plants open large, fragrant white flowers over one to a few consecutive nights.

Tohono Chul Botanical Garden in Tucson coordinates an anticipated mass-bloom viewing where hundreds to thousands of blooms can open simultaneously, producing a distinctive, short-lived spectacle.
