Coreopsis verticillata 'Designer Threads™ 'Scarlet Ribbons' is a compact threadleaf tickseed that brings rich, velvety maroon-red color to sunny beds and containers. You get fine, threadlike foliage that stays tidy as the plant fills out into a dense, mounded clump, topped by daisy-like blooms through the summer season. It is a strong choice when you want long-lasting color without a lot of fuss.

Plant it where it can enjoy full sun for the best flowering. Give it well-drained soil, and avoid spots that stay soggy after rain. Once established, it handles dry periods well, and it is also adaptable to leaner soils, making it a good fit for low-input plantings. Space plants to allow mature spread (about 16-20 in) so air can move through the foliage and the plant can branch freely.

In the garden, you can use it to edge paths, brighten a mixed perennial border, or mass it for a bold summer display. The flowers are attractive to pollinators such as bees and butterflies, and the plant is commonly noted for good tolerance of browsing pressure from deer and rabbits compared with many other perennials.

For maintenance, shear or trim lightly after a heavy flush of bloom to refresh the foliage and encourage more flowers later in the season. Deadheading can extend the display, but it is not required for performance. Cut back old stems in late fall or early spring, and divide mature clumps as needed to keep plants vigorous.
