Outstanding Qualities

Its small size and upright habit make Acer sieboldianum an excellent choice for the small garden. This slow grower has a narrow, upright crown that slowly broadens with age into a majestic form. The small star-like foliage colors in the autumn to a glistening red with shades of coppery orange. This maple is beautiful as either a single trunk or multi-stemmed tree.
