I have some weeds growing in the garden, but don't know what it is or how to get rid of it. Your help is appreciated.

I have an area of shrubs with barck mulch all around. I noticed these green shoots coming out of the mulch and decided to investigate. They have roots running under the bark mulch then into the soil underneath. I have been pulling at the roots, but they generally break and I suspect he roots go down deeper and revive to new runners over time. The runners underneath are sometimes a foot long.

Your weed is Field Horsetail (Equisetum arvense). To quote from Wikipedia (emphasis is mine):

It has separate sterile non-reproductive and fertile spore-bearing stems growing from a perennial underground rhizomatous stem system. The fertile stems are produced in early spring and are non-photosynthetic, while the green sterile stems start to grow after the fertile stems have wilted and persist through the summer until the first autumn frosts. Rhizomes can pierce through the soil up to 6 feet in depth. This allows this species to tolerate many conditions and is hard to get rid of even with the help of herbicides.

Here are a couple sources that discuss eradication:

Best of luck to you.
