I planted some greater yams, Dioscorea alata lastApril. They are usually planted in April and are harvested from December- January. Harvested one last Sunday, it turned out to be 5.7 kilos.
I normally dig out a hole of roughly one cubic foot and fill it with grass clippings, coconut husk fiber, leaves and kitchen waste mixed with the dug out soil. Then I plant a decent piece of dormant yam in it. The foliage grows as a wine, and I usually plant the yam near a tree so that the wine can crawl up the tree. When the leaves start dying off in the winter it is ready for harvest.
I have not tasted an arrowroot in years. I have been asking everybody to find me some to plant in my garden, but it was only last week a girl working in the hospital brought me a few small plants a root. I have planted them all, and keep you posted of their progress.
This is a plant that grows spontaneously in the lowland wet zone of Sri Lanka, and could have been an introduced species. My guess is that it belongs ginger family, the foliage looks similar to Turmeric. Folks here call it Artichoke, but I know a for fact that Artichoke is totally a different plant.
The plant has a rhizome that grows and sends up shoots.The roots sprouting from the rhizome bear potato like tubers that are delicious when boiled. If any body could help me identify this plant, I will be grateful.
