2. Broadleaf Tickseed, Coreopsis Latifolia

Native to the Blue Ridge Mountains, the Broadleaf Tickseed grows in moist forests with hardwoods and mafic rocks.

It’s thought to have once had a much more prolific range but is now rarely found even in its home of North California. It has yellow flowers and large leaves that can be almost 8 inches long and 4 inches wide.

Instead, the flower heads of the Georgia Tickseed are pink and purple.

6. Giant Coreopsis, Coreopsis Gigantea

It’s no surprise to learn that the Giant Coreopsis is one of the largest members of the Coreopsis group. The stem can grow up to 1 meter tall, with a diameter of around 4 inches, making it a trunk that stores water in dry weather.

The bright leaves and flowers decorate the top of the trunk, with the golden flowers reaching almost 8 inches in diameter. During the dry season, the branches and trunk turn bare.

7. Golden-Mane Coreopsis, Coreopsis Basalis

Lance-Leaved Coreopsis is a perennial plant that’s native to the eastern areas of the United States but is now found in many parts of the globe.

An invasive species in Japan and China, it was often planted for the pollinator properties provided by the seeds and nectar. Planting the easy-to-maintain Lance-Leaved Coreopsis can attract bees and butterflies to your yard.

A widespread Coreopsis that can be found from Mexico to Canada, the Plains Coreopsis is sometimes known as “Calliopsis.” It’s also found in China, where it has become naturalized.

The name “Tinctoria” comes from the dark red dots found at the base of each ray floret, which was once frequently used to make a dye for yarn. It was utilized by the Zuni people, who brewed a hot drink from the flower. And when women wanted a female child, they would drink a tincture made with the entire plant.

16. Sea Dahlia, Coreopsis Maritima

The Sea Dahlia grows around the coast and can be found on the ocean bluffs of San Diego and northern Baja. The lobed flowers can be seen coming into bloom as early as late winter and keep blooming until the early days of summer.

21. Woodland Tickseed, Coreopsis Pulchra

The Woodland Tickseed, a variety of Coreopsis so attractive it has earned the nickname “Beautiful Tickseed”, is actually at risk in its native home of the Southeastern United States.

It has a very narrow habitat and can only be found in the Cumberland Plateau of Alabama, although it may once have grown in Georgia.
