We do not know that this plant has flowered in American gardens, but we know of some plants that have endured our hardest winters. The following from the Garden indicates it to have some merit.

"This is a capital sea-side shrub, but thrives equally well in any good soil, and if a little salt be given old plants of it occasionally, it greatly improves their growth. This plant is propagated by means of seeds, by cuttings of the roots, and by grafting it on the Laburnum or the arborescent Caragana. When the latter, however, is used for the stock, it is apt to throw up suckers close to the ground, and, therefore, it is not so good for the purpose as the Laburnum, which does not do so. The name is derived from 'halimos,' maritime, and 'dendron,' a tree, in reference to the plant growing naturally in salt fields and saline steppes near the river Irtysh, or Irtish, in Siberia. It was first introduced in 1779. It forms an irregular, much-branched, deciduous shrub, from 4 feet to 8 feet high, when planted in the open border on its own roots; but when grafted standard high on the common Laburnum, it forms one of the most graceful drooping plants that can adorn a lawn or shrubbery. The leaves are alternate, abruptly pinnate, with two pairs of small leaflets, clothed with a whitish silky down, deciduous, and with the petioles and stipules spinose.

The flowers are of a fine rosy purple, sweet smelling, pea-shaped, tolerably large, and produced in great abundance on two and three-flowered peduncles, from the end of May to the middle of July, or even later, if the season be moist. The young plants, however, flower but sparingly at first; but when they attain size and age they bloom profusely. The pods are inflated, or bladdery, hard, ovate, brown, and contain but few seeds. Its synonyms are Robinia Halodendron, Caragana argentea, and Haloden-dron argenteum".
