Nicotiana (Flowering tobacco) Nicotiana 'Sensation' For many years 'Sensation' was the standard nicotiana mixture. It may be a little unpredictable in its colour balance, but its evening scent is heavy and penetrating and some of the individual plants, like this veined one, are simply lovely. Although prone to attack by greenfly and other aphids, plants are often sufficiently robust to flower well in spite of being infested. Type: Half-hardy annual Height: 3-4ft Season: early summer to first frosts Situation: Full sun to half shade, good soil   Nicotiana (Flowering tobacco) A-Z   ©copyright 1999 Graham Rice.
