Juncus validus

Juncus validus is similar to J. brachycarpus and J. polycephalus, which also have round heads and septate leaves. It differs from J. brachycarpus in that its capsule (like those of J. polycephalus) taper gradually and are equal to the perianth in length. It differs from J. polycephalus in that it is generally smaller, with a 3-5 mm diameter stem base, green sheathes, 3-6 mm wide leaves, and 12-15 mm diameter heads. Juncus polycephalus has a 10 mm stem base, purplish sheathes, 4-8 mm wide leaves, and heads that are about 10 mm in diameter. Green flat base. Round septate leaves, 2-3' tall.

The seeds of most species of Juncus may be planted fresh or after cold/moist stratification, and require light for germination (Steffen 1997).

Cattle graze it in late winter and early spring.

Wet open ground along ditches, streams and ponds, widely scattered localities, lake marshes and wet prairies.
