Like E. ciliatum, grows in a diversity of wet places, such as shores, stream banks, swamps (including tamarack), meadows, moist spots in forests, and ditches.
The seeds of E. coloratum are minutely papillose (as in most of its relatives), while in E. ciliatum the seeds are longitudinally striate, and this character may help with over-mature specimens when color of the hairs on the seeds may not be clear. The buds of E. coloratum are more abruptly contracted to distinct (sometimes spreading) sepal tips than is usual in E. ciliatum. This species also tends to flower and fruit later than E. ciliatum, with capsules dehiscing from late August to October, depending on latitude, season, and individual variation. Capsules of E. ciliatum may be found dehiscing as early as late June. In addition, E. coloratum is usually more bushy-branched.
