The flowers of the original flowering tobacco are very fragrant and open at night. Modern hybrids remain open all day, but are not always so fragrant or have no fragrance at all. What a pity that many new gardeners may never know the old fashioned flowering tobacco with its heady fragrance.

The modern hybrids are more compact growing and are free flowering for a long period in summer. The petals of the tubular flowers form a beautiful five-pointed star and are available in red, pale yellow, pink, lilac, burgundy, lime, green, and cream and white.

These shady garden classics are essential in cottage gardens. They are excellent cut flowers and attractive in border plantings, because their soft colours mix well with other perennials and annuals. The dwarf varieties are lovely in pots. Modern garden hybrids vary in height from 30 to 45cm tall.

These tough plants tolerate humidity and high temperatures. They grow well throughout South Africa in summer as long as they can be watered regularly and are protected from strong wind. They love to grow in semi-shade but will take some sun in cool regions. Plant them where they will receive full midday and afternoon shade in very hot areas. They love rich, moist, well-drained soil and must be watered regularly. Cutting back the old flower stalks after the first flush of blooms will encourage more flowers.
