TUCSON, Ariz. - On one night every year the Tohono Chul Park is home to a mass blooming of the world's largest collection of Peniocereus Greggii.

Plant experts at the park say they've been studying the plant for more than 20 years and still cannot figure out what exactly triggers the plant to bloom.

Bloom Night at the park is special for many reasons including the fact that plant experts cannot predict a bloom until the very day it's expected to happen.

Plant experts at the park said they are still not sure when the bloom will happen, but are hoping it will come soon.

Park staff encourage everyone to sign up for email alerts in order to know exactly when the bloom is expected to happen. You can sign up for email alerts by following this link.

There is also a Tohono Chul Park app that can be downloaded.

There is a $5 admission for non-members of the park and entrance is free for members.
