There are quite a few of these shrubs planted in the beds around the bus terminal here. There are both male and female individuals here (in different patches), which I have never seen before despite the fact that this species is pretty common in horticulture, so I thought it was a good opportunity to grab some comparison pics.
Overall, although both sexes still contain the vestigial organs from the opposite sex, the anthers are pretty clearly sessile and nonfunctional in the females, and the ovary pretty much absent in the males, making it pretty easy to distinguish between them.

In a wet to wet-mesic northern flatwoods
A few unusual sterile plants, lacking achenes, with Carex lupulina and Carex retrorsa nearby. The perigynia are generally ascending in the upper part of the inflorescences, as in Cx. lupulina, but they are spreading to reflexed in the lower part, as in Cx. retrorsa. The spikes are loosely arranged as in Cx. lupulina. But the lower spikes have staminate flowers at the tips, as in Cx. retrorsa. These plants are very likely a hybrid between Cx. lupulina and Cx. retrorsa
