Although this is a cultivated sedge (probably Carex elata 'Aurea') it offers a graphic illustration of sexual reproduction in this huge and widespread genus. The brown bits at the top of the flowering spikes are the remains of the male flowers after they have shed their pollen. Below them on the single spikes are the female flowers whose whitish stigmas will receive pollen and very soon start to form fruits – seeds between scales called glumes. The young leaves have still to extend, becoming a bright yellow that fades to green during the summer as the seeds turn black.
