Background

Native to Brazil, Langsdorff's tobacco is easy to pick out among flowering tobaccos by its small, nodding, tubular bell flowers in an unusual apple green, each one showing off a cluster of contrasting blue anthers when viewed from below. The airy, branching habit and unusual color make it a favorite for threading through borders where its green blends rather than competes.

It's grown as a tender annual everywhere outside the tropics, started indoors well ahead of the last frost since seed needs light to germinate and shouldn't be covered. It blooms from midsummer until frost and self-seeds readily in a spot it likes.
