Upright growing, relatively openly branched tree with a pyramidal crown that later becomes conical. ‘Excelsa’ grows vigorously to 15 to 20 m tall. The quite horizontal branches make the tree about 5 to 6 m wide. The bark is reddish brown, fibrous and flaky. The young twigs are green first, later turning reddish brown. Like the species, the lower branches can take root when they touch the ground and, seemingly form new trees. The scaly foliage is arranged in shingle form and glossy dark green, also in winter. When crushed the foliage gives off a characteristically pleasant fragrance. The blossom and the oval cones which follow are inconspicuous. Despite the slightly looser branching, ‘Excelsa’ is a fine hedge plant. Can also be used as a solitary or in groups.
