You got me there?
You can get this on eBay.
I found dragon fruit plants on Amazon for $10 and up. If you have a friend with a plant, you could ask for a cutting. This is a cactus, so it should be easy, if slow, to propagate. Good luck, Jewell.
I have purchased dragon fruit from krogers if they have one in your location
Publix has them last time I checked
Dragon Fruit can be bought at most grocery stores.
You should be able to find dragon fruit at the grocery store
