Anna's Magic Ball Arborvitae. This species is native to the U.S. and this is probably the most dwarf selection of the species getting to only 24-30" high with an equal spread. It has bright golden foliage which holds well in summer and winter when grown in full sun with good drainage. Because of its cold hardiness, it can be a feature plant in a container year around. It is a good foundation conifer that won't grow out of bounds. It was found as a branch sport of 'Danica.'
