We love Ruby Red Club Moss for its unique coloring and mounding habit. Its bright red stems accent the upright leaflets and dark green tops. Under cold temperatures, the foliage will turn red on the top but under normal growing conditions expect green on top and stems and underside to be the ruby red color. A slow grower, this selaginella, also known as spike moss, needs to be kept moist. And this is a perfect plant for little or no direct sunlight.
