From: RAYMOMATTLA at cs.com on 2005.05.21 at 14:25:10(12952) Colocasia gigantea is MUCH easier to grow..at least for me. In fact it has become somewhat of a weed. It is also very hardy to cold temps. Thin plants out in the spring if you want to get larger plants. I had one get a 10 foot spread when it wasnt competing with a dozen or so pups around it. Alocasia robusta gets bigger, but you need to be in a ultra-tropical location for it to attain gigantic proportions. It also seems more suseptible to rot. One suggestion for Alocasia robusta....Dont water it unless the soil is very dry.

From: Peter Matthews pjm at gol.com> on 2005.05.23 at 06:06:58(12953) 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.

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.

They're growing in the ground with a fairly heavy winter leaf mulch and have proven quite hardy, more so than C. esculenta. With lots of sun, water and fertilizer, they can make quite a specimen by the time frosty weather gets here, although not anywhere near their potential. I get fans of infloresences in good years that are interesting but never any seeds. When it rains heavily, the upward facing leaves tip the water out make for an interesting visual. I recall seeing a photo of them turned over and used effectively as rain hats in Vietnam. They make almost no tuber, so to overwinter them out of the ground, they must be potted up and kept moist to keep them alive. I think edibility must be somewhat variable with these plants. The Vietnamese lady that furnished mine said that they cook and eat the leaf petioles and tender new leaves like spinach, never raw. I've yet to try it that way but a Chinese friend decided to try a bite of an uncooked stem one time and one time only. The calcium oxalate crystals set her mouth and tongue on fire! She was even afraid to try it cooked after that, although cooking is supposed to neutralize that problem.

From: RAYMOMATTLA at cs.com on 2005.05.24 at 23:04:33(12959) I have lots of success with Colocasia gigantea here in the Upstate South Carolina area where we recieve temps near 10F every few years. In fact, I accidentally left a C. gigantea bulb out all year long....above ground, a few years ago, and it survived and sprouted. The low that winter was 19F at my house. C. esculenta is hit or miss and when it does survive it comes back slower and with less vigor than the C. gigantea. Both are doing well this year but it was a very mild winter, (with temps in the 70's nearly all the way through January.)

Linda << +More Dear Linda, "Malanga' is a generic Latin name for many root veggies, both Xanthosoma and Colocasia species/vars. There is a web page that gives many of the local names and their I.D.`s, but darn me if I know where it is and how to pull it up! Thy the IAS web site at MOBOT, I know that there were links to this page there. You MOST probably have one of the species of edible Xanthosomas, they are more commonly sold in Supermarkets, though I have seen on rarer occasions vars. of true Colocasia esculenta being sold as malanga Isleana or malanga cabesa. They are larger and almost round, while Xanthosoma vars. are longer, more flask-shaped.
