Dragon fruit!

The things you learn during drunken conversations in your backyard. I had noticed some flowers on the cacti that half-supports the old servants quarters in our backyard a few weeks back. I realized they were night-blooming flowers that close back up in the daytime. A much more gardening aware friend pointed out today that they are dragon fruit. Sadly I didn't get any shots of them fully open, and it seems its now too late in the year to flower again.

"The pitaya (also known as pitahaya, dragon fruit, huǒ lóng guǒ (火龍果/火龙果), strawberry pear, nanettikafruit, or thanh long) is the fruit of several cactus species, especially of the genus Hylocereus. Native to Mexico and Central and South America, these vine-like epiphytic cacti are also cultivated in Southeast Asian countries such as Vietnam and Malaysia. They are also found in Taiwan, Israel, and southern China. The pitaya only flowers at night, they are large white flowers that are often called Moonflower or Queen of the Night."
