This plant is commercially grown for human consumption in some parts of the world. However, it MUST (with no exception) be cooked correctly prior to eating. If any part is eaten raw it will cause SEVERE IRRITATION of the mouth and throat. The sap can also cause dermatitis.

PLEASE HANDLE WITH CARE.

You can chop up a bulb into 10 pieces and each piece will start a new plant. Does not like wind. Dappled shade/sun works best. Extremely fast growing...can spit out a big new leaf within 3 days. Can tolerate full sun if well established and watered often. I've seen 'em growing in water, not planted or nothing, just floating along...making baby plants as they go.

Most resources suggest shade to part shade. My best success is to plant in an area receiving 6 hours morning sun and bright afternoon shade. Rich, well drained, moist soil.

Grows like crazy in wet areas in central Florida. The size of the leaves is somewhat dependent on the size of the rhizome or tuber planted. I moved some that weighed about 50 pounds each and immediately got 4 foot leaves on 4 foot petioles. It will grow in standing water quite successfully - my best ones are in a drainage ditch that has had water all summer long.

However, it can be invasive - so don't discard rhizomes or tubers at the edges of natural wetlands in Florida or you could create a problem.

This grows well in Florida/ needs rich wet soil to produce a good crop of tubers-Mine grow well and are nice looking they do well in areas too wet for most things, [but not in standing water]. Be careful of your variety identification, --this looks like lots of other "non-edible" Xanth varieties ,when just looking at the folliage, the rest of the plant must be looked at before you determine that it is an edible variety, --to be sure to grow an edible variety buy some Malanga tubers from the market and plant some.
