Ancient and resilient, moss – flowerless, non-vascular plants that have survived for more than 450 million years, through different climactic conditions – represent some of Nature's tiniest habitats. Conor Knighton visits the Japanese-inspired Moss Garden at Washington State's Bloedel Reserve, where dozens of moss species are on display; and attends Lewis & Clark College's annual Moss Appreciation Week, where the beauty and wonder of moss can truly grow on you.
