I just bought a ZZ plant from Home Depot and I just love the look of it, but I had a couple of questions that I am having a hard time finding answers to on the internet. As you can see in the first photo, they cut some of the stalks (?) off leaving these abrupt stumps. Is there a way to make them grow again? Also, there are some dark black areas running up the outer edge of a couple of the stalks. They weren't there when I bought them. Could this be shock? I've only had it since Sunday, so I am hoping it will go away as it adjusts to my office.

It appears that they just cut away parts of the plant that were likely dead or near dead.
Many times plants that are sold in these type of garden departments are all loaded on the same rack together, and are watered on a schedule, not necessarily if the plant actually needed watering.
ZZ plants need only to be watered after the soil has dried out.
The cut parts of the plant will not regrow. An open wound on a plant can be susceptible to disease or even insects.
You can treat the plant with Neem Oil.
