Hoary yellowcress facts for kids

The hoary yellowcress (scientific name: Rorippa barbareifolia) is a type of plant. It grows in many different parts of the world, including Manchuria, Inner Mongolia, Mongolia, Siberia, Alaska, Yukon, and Saskatchewan.

This plant likes to live in wet places, but it doesn't grow completely underwater. You can often find it near the edges of forests, in ditches, or along the banks of streams.

What Makes It Special

The hoary yellowcress is an annual plant. This means it grows from a seed, flowers, makes new seeds, and then dies all within one year. It has bright yellow flowers, and each flower has four petals.

One of the most interesting things about the hoary yellowcress is its fruit. Its fruits are special because they have more sections, called valves, than most other plants in its family. Usually, the fruits of the hoary yellowcress have 3 to 6 valves, but most often they have 4. Other similar plants usually only have 2 valves, or sometimes 3. This unique feature helps scientists tell it apart from other plants in the Rorippa group.
