Rainy Side Notes
Sitting at my desk during the last hurrah of winter, I am imagining the wonderful fragrance of the flowering tobaccos in my garden once again. On any warm summer evening, the scent of a nicotiana reaches in through an open window, like a pied piper playing a fragrant tune, beckoning me to follow. To be without the flowering tobaccos and their lovely evening aroma is unthinkable for my garden. Nicotiana sylvestris, tall and stately in the garden, is a mainstay, no matter where I plant it. People passing by will stop and ask, "What plant is that?" They are pleasantly surprised when I tell them it is a tobacco plant. "But we don't smoke it," I quickly add.
Nicotiana, named after Jean Nicot, a 16th century French consul, introduced the plant to France. Sylvestris means of woods. In my trials with this plant, I notice in partial shade the leaves are much larger and deeper green. In sun, the leaves do not grow as large, and the leaves are almost chartreuse. In our maritime climate, we are blessed with flowers from summer into fall, unlike hot summer areas where the heat causes the plant to quit flowering. Some gardeners report that their plants reseed, but I have not had the pleasure of this miracle in my garden, at least not with this species.
Moths pollinate the white tubular flowers. The hawkmoths and sphinx moths are some that are attracted to the blossoms. If you ever see one of these beautiful large moths (they are almost the size of a hummingbird) going from flower to flower, you will be amazed by them. For this reason only, I would grow any white tubular flower with an evening fragrance.
All parts of the plant are poisonous.
