If it was not so lovely, it could be one of those carnivorous plants big enough to swallow a baby! The fruit starts with this "little" tight green upright bud with red tips. 
which unfolds while reaching for the sky.
Then, the flowers open wide for pollination
before it sort of bows to the ground, looses its petals and fades for the upright fruit to form at the base.
Fruits wrapped in netting go from green to red.
One bud starting out and another reaching full bloom (about 21 days from bud to flower).
The other flower fading away to give us the dragon fruit (another 30 days from flower to fruit).
Living in the city, I was fortunate that I could follow their journey over the 50 plus days.
