Dragon fruit

Dragon fruit grows on the Hylocereus cactus, also known as the Honolulu queen, whose flowers only open at night.
The plant is native to southern Mexico and Central America. Today, it is grown all over the world. It goes by many names, including pitaya, pitahaya, and strawberry pear.

They like warm conditions with mild winters and no frost and can tolerate the occasional short burst of cold weather but ideally they should be kept above 10 degrees. They can handle heat, drought, humidity and poor soils but will grow tastier fruit with regular watering and rich soil.

Choose a sunny spot and then boost the soil with compost and manure, or alternatively they will happily grow in a large pot.
