The 'Mushroom' is known for its mounded growth habit and its finely-toothed foliage that turns bronze-red in the winter. It has a very dense growth habit and will reach 2-3' tall and wide at maturity.
The 'Tansu' is a slow growing, dwarf variety that will get 3' tall and 2' wide after 10 years. It has a pyramidal, upright habit with light green, coarse foliage that takes on bronze tones in the winter. This variety makes a perfect specimen plant for a rock garden or container.
