Native of the Argentine, Brazil, and other parts of S. America; introduced in 1827. Although an ally of the common tobacco plant this is very different in general appearance, being an almost tree-like shrub of lax growth. It flowers from June onwards and is quite ornamental, the yellow flowers contrasting well with the vividly glaucous foliage. It was cultivated for several years in a sheltered sunny nook at Kew, but was not genuinely hardy there, being killed in hard winters. Even so, it is well worth cultivating, especially in the warmer counties.
In the warmer parts of the world it frequently escapes from cultivation and has even become naturalised.
