Laburnum is cultivated as a garden ornamental and occasionally escapes. The closely related L. alpinum (Miller) Bercht. et J. S. Presl is also cultivated but is not naturalised. It is distinguished from L. anagyroides by its more or less glabrous twigs, lvs and peduncles, and winged pod sutures. Cvs, especially L. 'Vossi', which have been developed from hybrids between the 2 spp., are also grown. L. anagyroides has been previously known in N.Z. as L. vulgare and Cytisus laburnum.
