Coreopsis ‘Last Dance’ (Photo by MT Cuba Center)<\/p><\/div>\n

Coreopsis (Coreopsis spp<\/em>.) are flowering perennials (and annuals) native to the eastern U.S. In 2016, MT Cuba Center* in Greenville, Delaware reported on the overall garden performance of 13 species and related cultivars and hybrids in the Mid-Atlantic region. Over a period of 3 years, the MT Cuba staff evaluated habit, floral display, disease resistance, and longevity. Several popular cultivars performed poorly because of disease susceptibility and winter survivability.<\/p>\n

Four underutilized native species and cultivars earned outstanding performance ratings. All four also displayed excellent resistance to powdery mildew, downy mildew, and leaf spot diseases.<\/p>\n

\u2018Summer Sunshine\u2019 coreopsis<\/strong> (C. palustris<\/em> \u2018Summer Sunshine\u2019) is the highest-rated coreopsis in the 3-year trial. Vigorous mounds of foliage grow to 30 inches tall and remain lush, sturdy, and dense all season long. In late September plants are covered with golden yellow flowers with dark central cones. The amazing display lasts for six weeks, and provided an important late-season food source for pollinators. \u2018Summer Sunshine\u2019 is a rhizomatous selection that slowly increases in size by 2.5 feet over three years.<\/p>\n

Coreopsis ‘Flower Tower’ (photo by Mt Cuba Center<\/p><\/div>\n

\u2018Flower Tower\u2019 coreopsis<\/strong> (C. tripteris<\/em> \u2018Flower Tower\u2019) appropriately named, towers over the competition at an astonishing 8 feet tall. Stems are thick and sturdy and capable of staying vertical in even the strongest winds. It is the tallest coreopsis in the trial, and also has the largest flowers, measuring 2\u00bd inches across. \u2018Flower Tower\u2019 is perfect for large-scale landscapes, perhaps not in average sized gardens. This rhizomatous selection spreads very slowly, about 2 feet over three years.<\/p>\n

\u2018Gold Standard\u2019 coreopsis<\/strong> (C. tripteris<\/em> \u2018Gold Standard\u2019) is another superior selection that typically grow to 7 feet tall, with a floppy habit and uninspiring floral display. \u2018Gold Standard\u2019 is a slightly shorter (5\u00bd feet tall) and has incredibly sturdy stems. By late July, a multitude of sunshine yellow flowers appear above the robust foliage in mid-August and the floral display lasts over two months. \u2018Gold Standard\u2019 has a rhizomatous habit and spreads slowly (about 2 feet over 3 years).<\/p>\n

\u2018Last Dance\u2019 coreopsis<\/strong> (C. integrifolia<\/em> \u2018Last Dance\u2019) is a fall-blooming tickseed whose uniformly compact habit is a vast improvement over other versions of C. integrifolia<\/em>. \u2018Last Dance\u2019 is slow to emerge in the spring. It often does not reach 1 feet tall until June, and eventually tops out at only 2 feet tall. The 2 inch, extra-large, golden flowers have strongly pleated petals which make them look thick and substantial. \u2018Last Dance\u2019 is the last tickseed to flower, blooming throughout October. \u2018Last Dance\u2019 spreads via rhizomes at a rate of about 12 inches per year.<\/p>\n
