SMALLanthus it ain't. A Cautionary Tale of Yaconquest

Like the anxious mother who fears for her daughter's ruin, I humbly beseech you to consider the following email I recently received from Gill Faiers of Bangors Organic before you plant yacon in your greenhouse:

Hi Owen

Neil has just dug up the Yakon

Oh my God! JCB was about right. I have no scales big enough to weigh the tubers but we estimate that it yielded about 20kg plus!!!!!!!!!!!!!!!!! from one plant

I do believe it could take over the world with this level of self generation

I am actually quite scared


You have been warned.
