Description
Plains Coreopsis Seeds 6905.
Bushy Canadian Native Annual for Vibrant, First-Year Colour.
Plains Coreopsis (Coreopsis tinctoria) is a charming Canadian native annual cherished for its bushy, multi-branched habit and profuse flowering display. Growing 60 cm or more in height, it produces masses of brilliant yellow blossoms accented by rich maroon centres. Ideal for adding instant, first-year colour to wildflower mixtures, garden beds, and borders, this self-seeding variety performs best in full sun but tolerates partial shade. It handles drier conditions well while thriving during seasons with average rainfall. The nectar-rich flowers are a favourite of local pollinators, while the seed heads provide valuable late-season food for small songbirds.
