Coreopsis tinctoria, or Golden Tickseed, is an annual that grows in most of the United States; it is native to the south-central US and Pacific Northwest, but it has spread to nearly all the rest through cultivation. It can either come up in the fall or in the spring - if it germinates in fall, it will overwinter as a small set of fern-like leaves, and it will quickly grow a tall stalk and bloom; if it comes up in spring, it will take longer to get to blooming size, and it will likely not form as big of a plant, as if it had had the whole fall and winter to grow energy. It grows in meadows, fields, prairies and along roadsides.

This plant is different from most other Coreopsis species, because it is an annual, and it also has leaves that are divided into a shape similar to fern leaves. The closest species are Coreopsis lanceolata, which has long, spear-shaped leaves and solid-yellow flowers, and Coreopsis basalis, which is a smaller plant and normally does not have as much red-brown on the flower petals as Coreopsis tinctoria.
