Rare on wet ground, either lowland or on hills. Stems to 100 cm high, c 4-9 mm diameter. Cone c 7-15 mm long. Skye ID: Stems are unbranched, with rough ribs each having 2 rows of tiny tubercles. Sheaths without teeth except when very young, but with a wavy edge where the teeth have fallen off. Other features: Forms very crowded stands that look like rushes, hence its name. Stems remain green through the winter and into the following spring. Sheaths eventually become white with a black band at top and bottom. Stems are slightly constricted at the sheath. Water Horsetail also has unbranched stems that form large stands, but its stems are extremely smooth whereas those of Dutch Rush are extremely rough (as well as other obvious differences) |
