Columnar tree with upright, slightly curving twigs creating a graceful winter silhouette. Strongly resembles B. pendula 'Fastigiata' but is less columnar and with less-curving twigs. The crown is loose and half open. Height circa 20 m. The trunk is whiter than of 'Fastigiata'. Older trunks get coarse, without the deep furrows like the species and turn to dark grey. Twigs are red brown and have wart-like lenticels. The triangular to rhomboid leaf has a coarse, double-serrated margin. 'Obelisk' sprouts early and has a yellow (brown) autumn colour. The leaf drops late. Hillocks, soil compaction and changing water tables have a negative influence. The tree is shallow-rooting. Does not withstand sea wind well. Winter hardiness zone: 2
