Help pruning Laburnum 'Vossi' (Goldenchain)

I planted this tree two years ago and it is growing vigorously, with great flower displays each spring. How should I prune it to encourage vertical growth? UW arboretum has some nice specimens at least 50 feet tall---but I don't know if they are the same variety. Maybe 'Vossi' wants to be more droopy.

Mine is growing out prolifically but doesn't seem to have a dominant leader. I tried staking the biggest branch upright but the whole thing is kind of floppy. How should I approach this? I have room for width but I don't want a shrub.

Your tree has already been developed by the nursery by this size. There is really nothing more for you to do except keep it growing well. It will look more like older, larger specimens you have seen when it is itself older and larger. Occasional low hanging branchlets that are bothersome to you could be snipped off, but the main branches are set and should not be messed with. Do not attempt to modify the main framework, in particular not cutting main branches off as these removals may result in cavities.

A short trunk with a vase-like arrangement of main branches on top is typical for these trees.
