Arborvitae fern, but it isn’t a fern at all! Actually its a really big spike moss! A moss with stems and arrow shaped fronds like a fern. To 10″ tall and forming a mounding colony in time. Bright green summer color is replaced by russet red and light brown with winter cold. Spreads slowly underground and new “fronds” unfurl out and up. With great age you’ll get a decent patch. So damn pretty for woodlands in the shade in rich, well drained soil that retains moisture- perpetually moist is what it wants. Its best home is in containers where it adds both a tough of doily green but 3D tiered layers as well. Regular summer moisture. Slow and easy does it. Its a moss! Can you dig it? Evergreen.
