Chorizanthe robusta is a special kind of flowering plant. It belongs to the buckwheat family. This plant only grows naturally in California. It is very rare and is listed as an endangered species by the government. This means it needs protection to survive.

What Does the Robust Spineflower Look Like?

The Chorizanthe robusta plant can look different depending on where it grows. It might spread out on the ground or stand up straight. It can grow up to about half a meter tall, which is like 20 inches.

This plant has a grayish color and is covered in tiny hairs. Its flowers grow in a cluster called an inflorescence. Each tiny flower is surrounded by special leaves called bracts. These bracts can be white or pink and have little hooked tips. The flowers themselves are very small, only a few millimeters long, and are usually white or pink.

Different Types of Robust Spineflower

There are two main types, or varieties, of Chorizanthe robusta:

  • Robust Spineflower (var. robusta): This type is found only in the southern parts of Santa Cruz and Monterey Counties.
  • Scotts Valley Spineflower (var. hartwegii): This type grows in just a few spots in Scotts Valley, which is also in Santa Cruz County.

The Chorizanthe robusta plant is closely related to another rare California plant called Chorizanthe pungens.
