Art & Materials

For artists, as for scientists, bryophytes (mosses, liverworts and hornworts) offer a world of untapped potential. Flying under many people’s radar due to their small relative size, these exceptional plants are deceptively gargantuan in ecological nfluence and stunning beauty, richly rewarding those who take the time to really look, and see.

In this preview presentation for the upcoming OBSA visit to the National Herbarium of Canada at the Canadian Museum of Nature’s Research and Collections facility in Gatineau, Quebec, we’ll meet the mosses and highlight just a few of the other exciting public resources that the Museum’s Herbarium Team safeguards for research, education, art and more.
