Ground cover

I have a LOT of what look like what I thought were Wandering Jews growing under ornamental palms but I was told they are not.  I asked the man who cuts my grass if he knew anyone who might want them so I don't have to just pull them up and throw them out and he said, "No.  They were popular for ground cover for a while, but they are very invasive and people stopped using them."

My question for David Goodman is:  Is there a use I am unaware of for them or is landfill a good choice?

Post some pictures - we can nail down the species.

Also - sweet potato makes a good ground cover if your climate allows and if you want something edible.
