Description: The leaves of all the various young plants of this originally garden-based invasive species were still green and OK-looking, despite two weeks of extremely frigid weather, including two nights in the single digits. All these small plants are ones that grew from small tubers that were accidentally overlooked when the gardeners were trying to dig out every plant of this species. In this wooded part of the Water's Edge garden, Italian Arum was planted years ago in a spot where nothing else would grow. However, it really got out of hand, and spread to cover a huge area. Now the problem is eradicating it, as these small plants easily escape notice. You cannot pull them up, as the leaves just break off leaving the tuber in place, and tubers can be quite deep in the soil. When you try to dig the plants up, always a number of tiny tubers escape notice. I did pull out all the fruiting spikes that I could find in the fall, so that at least the birds would not spread the plants by eating the berries and then wiping their beaks (or pooping) somewhere else.
