When you think of Kansas City, you may think of giant Oak trees, tall sunflowers, or gorgeous shrubs. Mosses are very likely not to come to mind in the City of Fountains. While they are a little unorthodox in their appearance and evolutionary strategy, mosses are some of the most interesting plants you can observe in the wild, even here in Kansas City. Minnie Reed, author of the first published flora of the mosses of Kansas, described them as “vagrants from every region in North America, as here is the middle ground where the different flora meet, or overlap.”

What makes mosses unique is their small and inconspicuous size and nature. There might be 10 different species of moss on one boulder, yet to the untrained eye it appears as one giant moss carpet. In a way, size plays to their advantage. They are able to exist at the boundary layer of airflow where the surface of the Earth meets the sky. In this “layer” is where water is kept moist and cool – allowing every dewdrop to satiate the mat of moss and prevent it from drying out. This strategy is what allowed plants to colonize Earth in the first place.
Mosses belong to a group of plants called the bryophytes. Bryophytes are unique in that they lack vascular tissues. Vascular tissues are the cells in many plants that are used to transport water and nutrients throughout their bodies. Mosses don’t transport water and nutrients; they just sort of live within a soupy concoction of substrate, nutrients, and water. This keep them happy, healthy and flourishing.
Prairies of Kansas, known to get drier and rockier as you head west, actually support many species of mosses. So in order to overcome dying out from the dry conditions, some mosses will “take a break” during the hottest parts of the year or when there is not enough water to go around. Their dormancy period protects them from death and lets them chill out until things are a little wetter and cooler.

Plants are unique compared to animals because they have two different “generations” when they reproduce. One of their generations is made up of half the number of genes, while the other is made up of a complete set of genes. Unlike other plants where the two generations are completely separate, mosses retain the two generations together. They are like nurturing mothers of the plant world, ensuring their little baby gets what they need before moving on to produce spores and move to greener pastures.
