Professor KALM (in honour of whom LINNAEUS, as before has been observed, named this genus of plants) in his travels into North-America, published in English by Mr. FORSTER, relates that he found this species in various provinces of that extensive continent, as Pensylvania, New-Jersey, and New-York, growing most commonly on the sides of hills, sometimes in woods; that it flourished most on the northern sides of the hills, especially where they were intersected by rivulets; he observes, that when all the other trees had lost their ornaments, this enlivened the woods by the verdure of its foliage, and that about the month of May, it was covered with a profusion of blossoms of unrivalled beauty.

Both MILLER and HANBURY recommend the Laburnum to be cultivated not only as an ornamental but as a timber tree, the wood having a very close grain, a good colour, and bearing a high polish;[6] they urge in its favour, that it is very hardy, a quick grower, and one that will thrive in almost any soil; the latter says, it will become a timber tree of more than a yard in girt: whatever success may attend its cultivation for the more useful purposes, as a hardy, deciduous, ornamental tree, it has long been the pride of our shrubberies and plantations. It blossoms in May, and is usually very productive of seeds, by which it may be propagated most readily. Hares and rabbits being fond of its bark, do great damage to plantations of Laburnum, especially in severe weather; I remember somewhere to have read, that these animals will not touch a tree if soot has been placed about it; perhaps, a circle drawn round the base of the tree with the new coal tar, which has a powerful smell of long duration, might keep off these noxious animals.
