Laburnum alpinum is cultivated as an ornamental tree. Plants can be successfully transplanted even when quite large. The most common ornamental Laburnum plant is a hybrid of this species and Laburnum anagyroides, Laburnum × watereri.

It can withstand strong winds but not maritime exposure and tolerates atmospheric pollution. The plant is notably susceptible to honey fungus.

Laburnum has a symbiotic relationship with certain soil bacteria, these bacteria form nodules on the roots and fix atmospheric nitrogen. Some of this nitrogen is utilized by the growing plant but some can also be used by other plants growing nearby.
