About Nicotiana alata 'Perfume Deep Purple'

Nicotiana alata 'Perfume Deep Purple' · also called Perfume Deep Purple Flowering Tobacco, Deep Purple Nicotiana · flowering

A compact, fragrant flowering tobacco from the Perfume series, 'Perfume Deep Purple' bears clusters of star-shaped, deep violet-purple trumpets that release a rich evening scent. Bred for tidy bedding and containers, it flowers continuously through summer and attracts moths and other night pollinators. It thrives in sun to part shade and rewards deadheading with steady bloom.

Mature size: Around 25-35 cm tall and 25-30 cm wide; the dwarf Perfume series is far more compact than species N. alata, which can exceed 1 m.

Indoor size vs how big it gets in the wild

Nicotiana alata 'Perfume Deep Purple' reaches its full size within one growing season — there is no "long-term" size, just how big it gets before you harvest or it dies back. Indoors and in a pot, expect around 25-35 cm tall and 25-30 cm wide. In the ground with no restriction it is a completely different plant — the dwarf perfume series is far more compact than species n. alata, which can exceed 1 m. — which is why the pot, the light and the pruning matter so much for the size you actually end up with.

It sizes up fast and once, racing from seedling to full size in a single season; after cropping it is finished, so size is a within-season question.

Growth rate and years to mature

Nicotiana alata 'Perfume Deep Purple' is a moderate grower. Realistically, expect a single growing season — it reaches full size in one year, then is done. Its feeding profile backs this up: feed every 2-4 weeks during growth and flowering with a balanced liquid fertiliser, or work slow-release feed into the bed at planting. steady feeding supports its continuous bloom; container plants need more frequent feeding than those in the ground.
