Corolla can mean two main things: a famous Toyota car model and a part of a flower.

1. Corolla as a car (Toyota Corolla)

When people say “Corolla” today, they usually mean the Toyota compact car.

  • It’s a series of compact (originally subcompact) cars made by Toyota since 1966.
  • It became the world’s best‑selling car nameplate in 1997, passing the Volkswagen Beetle.
  • Over 50 million Corollas have been sold worldwide across many generations.
  • It’s known for reliability, affordable running costs, and being an everyday “practical” car.
  • Modern Corollas come as sedans, hatchbacks, and related models like the Corolla Cross SUV in many markets.

In 2026, the Corolla is still sold as a safe, fuel‑efficient compact car, including hybrid versions that focus on saving fuel.

Quick example (car meaning)

“I’m thinking of buying a Corolla for my daily commute because it’s reliable and good on gas.”

2. Corolla in biology (part of a flower)

In botany, “corolla” is a technical word for part of a flower.

  • The corolla is the whorl of petals in a flower (all the petals together as a unit).
  • It usually sits inside/above the green sepals and is often the colorful part that attracts pollinators.

Quick example (flower meaning)

“Under the microscope, you can clearly see the corolla forming a ring of petals around the center of the flower.”

3. Which meaning is “right”?

  • Everyday conversation, news, and forums: “Corolla” almost always means the Toyota car.
  • Scientific or school biology context: “corolla” usually refers to the petal whorl of a flower.

So if you’re seeing “what is corolla” in car reviews, social media about vehicles, or 2026 auto news, they’re talking about the Toyota compact car line.

TL;DR:

  • Car: Toyota Corolla = long‑running, best‑selling compact car line from Toyota.
  • Biology: corolla = all the petals of a flower taken together, forming the inner whorl.
