Saguaro Cactus Blossoms — Image by kenne
Arizona’s state flower, the saguaro blossom, has a strong overripe melons smell, but I’m not going to get close enough to check it out — will leave that to the experts. Like a lot of cactus flowers, they are short-lived, blooming at night and often closed within 24 hours. During the night the flowers are pollinated by the lesser long-nosed bat and the Mexican long-tongued bat. During the daytime the flowers are pollinated by bees and birds such as the white-winged dove.

They look beautiful, but I can understand why you want to keep your distance.
