13/ Sissoo spinach, consistent short-lived perennial. 

Can be grown indoors. Needs a bit of shade. It really thrives well in heat. Doesn’t sustain any damage in tropical storms or hurricanes. Does need nitrogen. I grew beans in a pot with them and the spinach did well with them. Not a water hog, just watch for them getting a little wilty. 

Propagates by cloning. A few sprigs should be cloned once a year to replace old ones that eventually give out.
