Most ornamental nicotiana species are prized for their flowers, but with tree tobacco (Nicotiana glauca), the smooth, powder-blue foliage is the key feature. It does flower too, with clusters of tubular, yellow blooms from midsummer to frost, but that’s more of a bonus feature as far as I am concerned. In mild climates (where, by the way, it may be considered invasive, so please research it in your zone before buying), this species is actually a large shrub or small tree, but you can grow it as an annual pretty much anywhere. And when you do that, expect the plants to reach around 6 to 8 feet by the end of the growing season, with sparse branching unless you occasionally pinch off the stem tips.
Tree tobacco is valuable for adding height, texture, and foliage color to a border or even a large container. I have also used it as a natural support for a lightweight annual vine, such as climbing snapdragon (Asarina scandens). (If you try that, plant the tree tobacco first and wait until it’s at least a foot or so tall before adding the vine.) Full sun to light shade.
For ornamental use only.
