The Mexican Bluebell—scientifically known as Ruellia brittoniana or Ruellia simplex—is a resilient, fast-growing flowering plant recognized for its vibrant, trumpet-shaped blue to purple blooms. Often referred to as wild petunia or Britton’s wild petunia, this plant adds both aesthetic beauty and ecological value to the landscapes it inhabits.
What is Mexican Bluebell?
Mexican Bluebell is a perennial flowering plant belonging to
the Acanthaceae family. Despite its common name, it is not a true petunia. The
plant is characterized by:
- Narrow,
lance-shaped dark green leaves.
- Showy
blue to violet flowers that bloom profusely, especially in warmer
climates.
- A
shrubby, upright growth habit that can reach 2 to 3 feet in height.
It thrives in a variety of soil conditions and is often used
in ornamental gardening, due to its low maintenance requirements and long
blooming season.
Where Does Mexican Bluebell Come From?
Originally native to Mexico, Central America,
and parts of the Caribbean, the Mexican Bluebell has since naturalized
in various regions around the world. It is especially prevalent in:
- Southern
United States (notably Texas and Florida)
- Southeast
Asia
- Australia
In some regions, it is considered invasive due to its
ability to spread rapidly, particularly in wetlands and along roadsides.
Benefits of Mexican Bluebell

Mexican Bluebell grows abundantly in:
- Southern
Mexico and Central America: As part of its native habitat, it thrives
in natural and semi-natural environments.
- Florida
and Texas (USA): Widely planted and naturalized; in some areas, it has
become a common wildflower.
