Tiny stars of the wetland: a close-up of the distinctive seed clusters of a Starred Sedge (Carex species).
The Intriguing Starred Sedge
Out in the wetlands of northwestern Ontario, a fascinating plant often goes unnoticed, easily mistaken for common grass. This is the Starred Sedge (Carex species), a distinctive member of the sedge family.
Its most striking feature is found on its stems: small, intricate clusters that spread out like miniature stars, a truly unique sight among the surrounding greenery. This unassuming plant thrives in the moist, rich soils of bogs, fens, and along the edges of streams, its narrow, grass-like leaves forming dense clumps in these vital habitats.
Unlike true grasses, sedges like this one have distinct triangular stems (though you’d need a close feel to notice that!). What truly sets the Starred Sedge apart are those distinctive, star-shaped clusters. These aren’t flowers in the traditional sense, but groups of perigynia, small, sac-like structures that will eventually hold the plant’s seeds. In our region, you’re most likely observing a species from the Carex echinata complex, thriving where the ground stays moist.
These remarkable sedges are masters of their environment, preferring wet conditions found in bogs, fens, and along the muddy edges of streams and lakes. They often grow in dense clumps, forming intricate mats of narrow, grass-like leaves that add texture to these vital habitats. It’s those unusual, starry seedheads, however, that consistently draw the eye and spark curiosity.
