Laburnum, the Broad-leafed, Cytisus laburnum, L. a valuable exotic tree, introduced from the Alps, into the Highlands of Scotland.

This plant is very hardy, and will thrive on poor shallow lands, and in exposed situations: it is propagated by seeds, which should be deposited in March, in a light and rather moist soil, where the tree is intended to remain ; and, in the succeeding month, young shoots will appear. But, if sown in autumn, the seeds do not germinate till the following spring.

The broad-leaved laburnum forms an agreeable ornament for parks and gardens ; as it grows rapidly, with a straight stem, and, in the course of four years, is generally twelve feet high.-its wood is frequently employed on the Continent, and in the Highlands, for making chairs, tables, and other articles of household furniture, which are said to resemble the finest mahogany. - Suckow re-marks, that a decoction of the fresh branches and leaves of this tree, imparted an excellent dark-brown colour to cloth prepared in a solution of green vitriol.
