How to Grow Flowering Tobacco — Nicotiana

Sharing is caring!

Nicotiana, commonly called flowering tobacco, produces clusters of tubular-shaped, five-petaled flowers in green, white, cream, and several other colors. Flowers appear from summer to early fall and are long-blooming.

Nicotiana is an upright perennial grown commonly grown as an annual. Most nicotianas have large, oval, mid-green leaves. Some cultivars are a foot and a half tall others tower to 4 feet or more.

Nicotiana is an excellent bedding plant for regions with hot, humid summers. Old-fashioned types close for part of the day and open in the evening with a strong, sweet smell. White varieties are especially attractive at night. New hybrids stay open all day and evening.

Nicotiana is an excellent choice to mass in borders; plant twelve or more plants for a showy display. Nicotiana can also be planted in containers; space close and feed with a liquid fertilizer. Nicotiana is a very good cut flower.
