I brought the hosta with me from Utah when I moved last year, and it had been in the ground at least 5 years before moving. I never saw anything like this in my yard in Utah, so I'm pretty sure it didn't tag along. It's very interesting, whatever it is. Am I correct to assume that it's not actually a weed? The last thing I need around here are more weeds!

That depends on what you consider to be a weed and which species it actually is.

Some species are extremely invasive, such as Japanese Knotweed (Polygonum cuspidatum/Fallopia japonica/Reynoutria japonica) and Giant Knotweed Polygonum sachalinense/Fallopia sachalinensis/Reynoutria sachalinensis). The hybrid between those two is even worse! Your plants don't look like any of those, though.

On the other hand, many of the native species are considered to be valuable wildlife plants and some are even grown as ornamentals.
