This one is old news for most of the old timers here, but I figured I'd just go back over this interesting fact about kava again. It really says something to me that kava has to have a human touch in order to live. Kava and man are very much a mutualistic symbiotic relationship. I know it's not the only plant we've cultivated to sterility, but there's something special about it in kava's case, at least to me.
Throughout the millennia of kava cultivation, kava lost its ability to produce seeds and reproduce by expressing a "self-incompatibility mechanism" or SI. This occurs in flowering plants to prevent inbreeding and promote outcrossing.
New kava growth develops from burying stem nodes in soil. Roots develop off of the node, and in 3-5 years the plant is harvested.

Linked below is a patent for kava cultivation. It's quite interesting in that it seems to suggest planting kava in raised beds. Cultivation of the roots looks simplified by using some sort of "rake" attachment to a forklift and just lifting the entire root collection at once.
