Can Dragon Fruit Survive the Seattle Winters?

I was getting a bit tired of having my Dragon fruit inside so I threw it out on my deck for Summer. We'll it did nothing but grow. And now that I have 2 young kids in the house. I didn't want a prickly vine cactus accident to happen, so I left it out on the deck but next to the sliding glass door. So far so good. No frost damage even after 2 snowfalls. The heat coming off of the sliding doors has pretty much kept the Cactus safe from frost.

I'm glad because this thing is only going to get bigger with time and I do not want to drag it back into the house.

My Jaboticaba has also done surprisingly well on the deck. It's still holding all of it's leaves. I may want to try the Jamaican cherry as well out on the deck. It can withstand down to 28F temps. But next to the sliding glass door on the deck, I'm sure it won't dip below 32F. But since it's my only tree, I do not want to risk it until I can create a clone.

2017 Update on my Dragon Fruit

I think I've been growing my dragon fruit now for a 3yrs. Honestly, I do not do a great job of taking care of it. It's because if grows so out of control! and I have 300 Fig pots that occupy my time.

It's got prickly spines and likes to behave like a vine, making it a bit treacherous to get snagged on. I have a tomato trellis hold it up. but it's getting a bit heavier than the trellis can handle.

So far it loves being in partial sun on the deck. You can see the difference between indoor and out door growth. The indoor growth is much more skinny and lanky.

Typically these dragon fruits can take up to 6yrs to fruit so I'm not holding my breath waiting for it to flower. For now I will continue keeping this plant for another few years. I'm determined to see it fruit!
