Nicotiana (Flowering tobacco) Nicotiana langsdorfii This delicate yet prolific green-flowered species is always admired. Its dainty bells are open, airy and dangle at quirky angles; look under the skirt and the blue anthers sparkle like sapphires. Perhaps a little hardier than other species, but even so rarely hardy in most of Britain (zone 8), N. langsdorfii often self sows, especially in gravel, to produce unexpected associations - I esepcially remember the year it emerged through a mass of white galegas. Type: Half-hardy annual (perennial in zone 9 and above) Height: 2-4ft/60-90cm Season: early summer to first frosts Situation: Full sun to half shade, good soil Nicotiana (Flowering tobacco) A-Z   ©copyright 1999 Graham Rice.
