Title: Re: [Aroid-l] Alocasia robusta & Colocasia gigantea
Thanks for asking...

Colocasia esculenta (sat-imo in japanese) is the main species grown, usually for the corms, but some cultivars are also used as stem vegetables.

Colocasia gigantea (hasu-imo in Japanese) is only grown as a stem vegetable, with an almost completely non-acrid petiole (can be peeled and then sliced thinly and eaten as a vinegared pickle).

A single clump of C. gigantea here and there is common in home gardens, but there are also many commercial producers with entire fields of the plant, in warmer southern areas.

Both species are summer crops here.

Dear Peter,

I THINK the Colocasia being grown as a leaf-veggie in Japan may be Colocasia e. esculenta, NOT Colocasia gigantea, the latter may be a less cold hardy species!
Please let us know.

Thanks,

Julius
 As an edible stem vegetable (cultivar only, not the wildtype)  Colocasia gigantea grows as far north as about 35 degrees N. in  Japan. Here it is a summer crop that can be left in the ground over winter,  with mulch and soil to protect the apical tips from cold damage (can  survive this way under snow). Under these conditions, it does not grow so high as in the tropics,  but it can still be a pretty plant.
