In similar habitats as the closely related Juncus effusus: marshes, shores, banks of ditches and streams, bog borders, pastures, etc., but perhaps less common.

Often a smaller plant than Juncus effusus, but with tepals often longer than those of J. effusus, the larger being 2.5–3.8 mm long and consistently longer than the capsules at maturity

The Old World Juncus conglomeratus L. has been collected in Algoma District, Ontario, and may be found in Michigan. It has three stamens and ridged stems like J. pylaei, but the inflorescences are densely congested.
