Mushroom

Unusual dwarf mound cryptomeria that looks like a mushroom cap on the ground.  In spring and summer the color is a medium green, while the winter color is  a lovely bronze color.  This plant is new to us, so we are uncertain how big it will get, but our plant has been in the garden for 5 years and is about 3 ft. tall and around 4 ft. wide.  Needs no pruning.
