This reminds me of my sense of hopelessness with these prolific Asian Yam plants and the utter sense of futility of ever getting them under control in the gardens of Richmond Hill! After 2-3 Years(!) of trying to eradicate this particular invasive plant, I was in tears when just a tiny patch yielded over 30-40 NEW plants in the newly-planted Grace St garden in just a month or two! That patch, totally intermingled with the new plantings, took me over 2hrs to clear all the yams…and I know a portion of them left growable pieces that will re-sprout! The rest of the new Grace Street Garden has other patches of this kind invasive species, but not as innumerable as the patch I just attempted to clear.

But, as in Beth’s story, my time in the Richmond Hill Gardens has a way of “going home with me!” Several hours after I had returned home, a possible lesson of this particular invasive ”gem” came to mind. The success of this plant to literally -Invade- this huge garden space, the WHOLE plantable space from year to year, was due to the way it produces so many twin seed pods every 4-5” of growth just before the fall season.

All these years, I had been attacking the plants themselves by digging each plant up, not paying much thinking to the fact that the yam vines climbing up tall trees could possibly release as much as 15x2 seed pods PER PLANT!!

So, what was the plant’s SAVING message to me? Simple—cut each vine off down to 2 leaves (so I can find them) BETWEEN NOW AND SEED-SETTING TIME, so the population of seeds dropping
