13. Nicotiana
Nicotiana, commonly known as flowering tobacco, may not sound glamorous, but don’t let the name fool you—it’s one of the most pleasantly surprising fragrant plants you can grow. This tall annual features trumpet-shaped flowers in shades of white, pink, green, and burgundy, and releases its scent most strongly at dusk and into the evening. The aroma is floral and slightly sweet, with a mysterious edge that makes it feel perfect for moon gardens or late-night outdoor spaces. Nicotiana grows easily from seed and does well in both borders and containers. It prefers full sun but can handle light shade and needs well-drained soil to thrive. Some varieties are ornamental hybrids and less fragrant, so choose heritage types if scent is your priority. These plants also attract night-flying moths and beneficial insects, adding to their nocturnal magic.
