A weeping form with a top that does not grow upright. Usually grafted at a height of circa 2.5 m. The crown, which is strongly branching and horizontal, starts at the graft union. The branches are gracefully pendent, creating an umbrella-shaped tree. The eventual height depends strongly of the height of the graft union. Width of the crown can be circa 6 - 8 m. As rootstock the Betula pendula is used. The twigs are red brown and have warty lenticels. the leaf is triangular and linear pointed and has a double-toothed margin. The autumn colour is strikingly yellow, 'Youngii' rarely flowers. Hillocks, soil compaction and variable water levels have a negative influence on the health of this birch. The tree is shallow-rooting. Sea wind is not tolerated well.
