Nicotiana langsdorffii - Langsdorffs tobacco Seeds

Nicotiana langsdorffii is a species of tobacco plant with astonishing trumpet-shaped blooms in a very tangy shade of lime-green that droop delicately in very loose clusters. 

Nicotiana or tobacco plant is a member of the Solanaceae family and comes from the tropical and subtropical regions of South and Central America. It blooms profusely throughout the warmer seasons until the first cold spells. Still rarely used in French gardens, tobacco plants would gain to be known for the originality of their often deliciously scented flowers and the exotic touch they bring to gardens. Most species of tobacco produce flowers that open in the late afternoon, diffusing their jasmine-like scent all night long, and close in the early morning, at first light. These plants are described botanically as being vespertine. Some modern hybrids now offer daytime flowering with blooms in a variety of shades.

Nicotiana unfold their inflorescences, displaying loose, raceme-like cymes. The long calyx made up of 5 fused sepals, encircles the base of the corolla and once the flower wilts, hosts the tiny seeds. The corolla is composed of 5 petals fused into a tube that divide, flaring sharply into 5 slightly indented lobes that form stars from which 5 long stamens shoot out. As for the leaves, they are often covered with a short glandular down which exude a viscous, sticky substance.

The astonishing Nicotiana langsdorffii blooms all summer, from July to October, bearing a profusion of long, lime-green flowers that droop slightly. This very fragrant variety has large, velvety flowers that measure 5 cm in diameter and is very easy to grow. The flower is barely indented and the petals do not present distinctive lobes. This variety is very original and very easy to grow. The plant can easily reach a metre in height and can sometimes even reach 1.5 metres.

Nicotiana love full sun or light shade in well-drained soil that is consistently moist without being wet and positions sheltered from the wind. They will look wonderful in mixed borders, bed edges or in large container displays on a patio. They are an unparalleled choice for creating a symphony of colours and textures along with Cosmos bipinnatus, Eryngium giganteum, the spider flower Cleome Colour Fountain or Salvia horminum.

Did you know that the way Nicotiana plants are pollinated is directly related to the nicotine content of the flowers? Indeed, research has shown that varieties with low levels of nicotine need bees, butterflies etc. to pollinate them. In fact, the scent of the flowers is supposed to attract them. On the other hand, varieties with very high levels of nicotine can be lethal to insects. They have since then adapted by turning to self-pollination. How else can this be achieved if the handiwork of the pollinator is compromised?

Warning: seeds are best meant for very experienced gardeners who are used to sowing very fine seeds. These seeds are as fine as dust and are hardly visible to the naked eye.
