What is the botanical name for the cigar plant that is recommended as a perennial?

The botanical name for the cigar plant, which is recommended as a perennial, is Cuphea micropetala. This plant is known for its vibrant tubular flowers that attract pollinators such as hummingbirds and butterflies, making it a popular choice in ornamental gardens. As a perennial, it can thrive in a garden setting for multiple years with proper care, contributing both aesthetic appeal and ecological benefits.

The other plants mentioned have different characteristics and uses. Tagetes lucida, commonly known as Mexican tarragon or sweet marigold, is favored for culinary uses and is less known for its ornamental value. Hamelia patens, commonly called firebush, is indeed a perennial but not typically referred to as the cigar plant. Canna x generalis, known as canna lily, is a tropical plant often grown for its large, striking foliage and flowers; however, it is not classified as the cigar plant. Thus, Cuphea micropetala stands out as the correct answer due to its specific identity and perennial status in horticulture.
