here's young one in a pot:
(first time posting a pic here, hope i got it)
native to bolivia, member of the sunflower family (like jerusalem artichokes) that make tubers that taste kinda sweet/sour and crunchy, a bit like an apple but with a less granular sort of structure. from what i've read, they're not anywhere near as invasive as jerusalem arti's can be and have a slightly weirder root-growth style...they have a 'crown' of rhizomes that are generally purple in color and shoot out shoots for all the aerial growth, but they also make storage tubers (that's the main thing eaten). they're perennial, though they apparently can't winter over outside where i am, gotta bring in the rhizomes in the fall, when you dig the tubers...the plants can get 3-5 feet tall and have 4" blooms, really softly fuzzy leaves. probably pretty darn attractive in high summer (will post more pics if this is the case!)
anyone ever seen one of these before? anyone grown them? if so, anything to look out for?
