Lance-leaved coreopsis is one of those great plants that looks good in the border as well as in a meadow. It is long blooming and tough and spreads into vigorous colonies that are easily transplanted anywhere their bright yellow color is needed. A native of central and southeastern United States, it thrives in meadows, prairies, and roadsides and tends to sprawl in fertile moist soil. It even does well in a vase and gives a cheery look to any arrangement. Attractive cultivars such as ‘Sterntaler’ are available.
