Dragonfruit Flower

[isurus79]

This is a very common cactus that you can find all over the drier regions of Hawaii, including the rock wall behind my house where I grow most of my orchid collection. Hylocereus undatus is the scientific name of the cactus (Google it for more info, its pretty interesting!) and the flowers open only for one night and are HUGE!! The second pic includes my hand touching the petals for size reference. I also swished my fingers inside the flower, hoping to fertilize it so I can get some of the yummy dragon fruit (or so I hear!) soon! Very cool!
