There is cause to visit cranberry bogs in a month already but in the silence and enchantment of the bogs there are always ramblers.
The Rannoch rush that now is yellow with fruits grows in wet hollows and overgrowing puddle (hag) verges. How is it possible to grow in peat moss in such places? The air-containing tissue in the rhizome of the Rannoch rush “produces” oxygen aided by which it draws nutrients from the deeper layers of the peat where the oxygen deficiency is so great that the roots of other plants would simply perish.
It has to feed the knotty stem, the leaf blades that resemble chives somewhat and the inflorescences that carry quite conspicuous yellow fruits, three to four together. The seed in the fruit is light brown and shiny and floats in water.
