SuperMoss Wood Moss or Excelsior is made from fine Aspen wood shavings that twist and curl. It is a cellulose base, so it lasts forever and sustains watering. It comes in a wide variety of colors, so it is easy to pair with flower color or home and garden décor. Our thinly shaved wood Moss is also an exciting liner for presents, gift baskets, and picnic baskets. Available in SuperMoss retail packaging or in bulk quantities.
