I've grown yacon for a two years now, but I realise I've never posted about it -thanks Dixiebelle for the reminder . What is it? I hear you ask - it's a crunchy tuber vegetable, aka Peruvian Ground Apple . I've grown it successfully here in the least frosty part of the garden near the water tank - always planting out after the last frost has passed.
This year I planted four plants, and I have a generous basked full of tubers. Raw they have a lovely crunchy apple/cucumber like mild flavour (peel the skin and the white part) - great for a salad.
