Inspecting the same farm in September last year, Kim had ordered the establishment of a high-tech agricultural and science think tank.

Is that leafy vegetable Khat ..? ..The effects of khat (also known as qat, qaad, Arabian tea, kat and chat) are similar to those of other amphetamines, according to authorities like the Drug Enforcement Administration. Khat users report feelings of well-being, mental alertness, excitement and euphoria.

Or perhaps Arugula .....arugula is also a bit of a powerhouse when it comes to the nutrients necessary for a thriving sex life. It is rich in vitamins A and C, which are essential for sex hormone production. In addition, it delivers many minerals that are important to put the body in its sexual prime. Its a source of zinc, excellent for promoting good blood flow to the nether regions, as well as sex-aiding minerals magnesium and potassium.

My best guess is that the Norks produced a hybrid Arugula-Khat plant.

Arugula, a close cousin of dandelion is somewhat bitter, and excessive use produces chronic loose stools, and a general sense of malaise.

Not a good choice for an army!

Just looks like a Kentucky Bibb hybrid with, well, possibly arugula, yeah, but more likely spinach or even kale, although kale hybrids tend to look like kale.

Or maybe tobacco lol...
