This is the seedhead of a very hardy grass that we call elephant grass here. It’s a bit of a pest, in my opinion, because the leaves are sharp (no good for weaving- you’ll cut up your hands) and the roots are so strong it’s impossible to pull up. You’ll only hurt yourself if you try. Perhaps it’s named elephant grass because you’d need the strength of an elephant to move it? It grows about 5 feet tall and provides good privacy and can withstand freezing temperatures, drought, and seasonal flooding and doesn’t take much effort to maintain, but I still don’t like finding seedlings of it in my garden. Even when the plant is small, it is incredibly difficult to pull up. A single plant with just a few blades of the sharp grass takes all my strength to remove.
In the winter, when everything else has died back, it’s rather pretty to look at. I took this photo earlier this month, and since then, a neighbor’s cat has moved into the grass and made it her home, so I don’t disturb that area right now.
