About the Hill Suncup

The hill suncup is an annual herb. This means it completes its whole life cycle, from seed to flower to new seeds, all within one year. It usually doesn't have a main stem that stands up tall. Instead, it grows a cluster of flowers that nod, or bend downwards, at the top.

What it Looks Like

This plant has narrow leaves that grow in a group. Each leaf can be anywhere from one to ten centimeters long. The flowers are bright yellow and can be about one half to two centimeters long.

How it Grows

After the flowers bloom, the plant produces a fruit. This fruit is a bit like a leathery capsule, which is a dry case that holds seeds. It's usually less than a centimeter long. Inside this capsule, there are four small sections, and each section contains bumpy brown seeds.
