Are there any Cuphea species that are considered rare or endangered?

The provided information regarding the Cuphea genus focuses on its general characteristics and common species used as ornamentals, but it does not contain data regarding the conservation status of specific species. Therefore, I cannot confirm which, if any, Cuphea species are currently classified as rare or endangered based on these results.

How many species are included in the Cuphea genus, and what are some notable examples?

The Cuphea genus consists of more than 200 species of herbs and shrubs, primarily native to tropical America and belonging to the family Lythraceae. Four species are frequently cultivated as houseplants for their ornamental flowers:

  • Cuphea hyssopifolia (elfin herb): A small, branched, hairy shrub featuring narrow leaves and tubular violet-white flowers.
  • C. llavea: A hairy plant reaching up to 60 cm (2 feet) in height, characterized by rough, oval leaves and red tubular flowers.
  • C. micropetala: A taller species (30–120 cm) with oblong leaves and tubular flowers that are yellow with a scarlet base.
  • C. platycentra (also known as C. ignea or cigar flower): A smaller plant (20–37 cm) with lance-shaped leaves and distinctive reddish tubular flowers featuring a dark ring and an ashy-white mouth.

How are Cuphea plants used in horticulture and landscaping?

In horticulture, Cuphea plants are primarily valued for their aesthetic appeal and are commonly grown indoors as ornamental plants. The genus includes more than 200 species of herbs and shrubs, with four specific species native to Mexico and Central America frequently utilized for their attractive, distinctively shaped flowers.1

These species are popular in indoor settings due to their varied growth habits and floral characteristics:

  • Elfin herb (Cuphea hyssopifolia): A small, branched, hairy shrub favored for its dense, narrow leaves and tubular violet-white flowers.1
  • Cigar flower (Cuphea platycentra or C. ignea): A compact plant known for its lance-shaped leaves and unique reddish tubular flowers, which feature a dark ring and an ashy-white mouth.1
  • Other varieties: Species such as C. llavea and C. micropetala are also grown for their ornamental value, offering different heights and vibrant color profiles, ranging from solid red to yellow with scarlet bases.1

While these plants are widely recognized for their role in ornamental horticulture, the provided information does not detail specific outdoor landscaping applications or broader commercial uses.

Several Cuphea species are known by descriptive common names that reflect their physical appearance:

  • Cigar flower (Cuphea platycentra): This species is named for its tubular, reddish flowers, which feature a dark ring and an ashy-white mouth, resembling the appearance of a lit cigar.1
  • Elfin herb (Cuphea hyssopifolia): This name refers to the plant’s small, delicate stature and its many-branched, hairy shrub habit.1

The name of the genus itself, Cuphea, is derived from the New Latin word based on the Greek kyphos, meaning “hump.” This refers to the distinct protuberance found on the plant’s calyx tube. While some sources also reference the name “waxweed” for the genus, the specific etymological connection for that common name is not detailed in the provided records.3
