Coreopsis ‘Gold Standard’<\/p><\/div>\n

C. ‘Gold Standard’<\/p><\/div>\n

In 2016, Mt. Cuba Center in Greenville, Delaware reported the garden performance of 13 different perennial coreopsis (tickseed) species, hybrids, and related cultivars native to the eastern U.S. Over a period of three years, plants were assessed for their habit, floral display, disease resistance, and longevity. In the trial many popular tickseed cultivars performed poorly because of disease and winter survivability.<\/p>\n

Four new selections<\/strong>\u00a0were recognized and named because of their outstanding performance in\u00a0the trial. The following plants, listed in order starting with the highest rated, are among the top-performing coreopsis.<\/p>\n

    \n
  1. \u2018Summer Sunshine\u2019 coreopsis<\/strong> (C<\/em>. 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. The attractive foliage erupts in late September with a sea of golden yellow flowers with dark central cones. The amazing display lasts for six weeks, providing an important late-season food source for pollinators. \u2018Summer Sunshine\u2019 is a rhizomatous selection that slowly increases in size by 2\u00bd feet over three years. It has superior growth habit and disease resistance.<\/li>\n
  2. \u2018Flower Tower\u2019 coreopsis<\/strong> (C<\/em>. tripteris<\/em> \u2018Flower Tower\u2019), appropriately named, towers over the competition at an astonishing 8 feet tall. This tall\u00a0cultivar does not flop\u00a0with thick, sturdy stems, standing up to the strongest winds. \u2018Flower Tower\u2019 was the tallest coreopsis in the trial and has the largest flowers (2\u00bd\u201d). During the month of August, they create a wonderful display swaying atop the lofty stems. \u2018Flower Tower\u2019 is perfect for large-scale landscapes, but a challenge in average sized gardens. C. tripteris \u2018Flower Tower\u2019 is a rhizomatous selection that spreads very slowly\u2013 about 2 feet over 3 years.<\/li>\n
  3. \u2018Gold Standard\u2019 coreopsis<\/strong> (C. tripteris<\/em> \u2018Gold Standard\u2019) is a superior selection of tall tickseed (C. tripteris). C. tripteris<\/em> grow typically to nearly 7 feet tall, has a floppy growth habit and subpar floral display. But \u2018Gold Standard\u2019, collected in Alabama by Mt. Cuba Center, is slightly shorter (5\u00bd feet\u2019 tall) and incredibly sturdy. In late July, multitudes of bright yellow flowers appear above the vigorous foliage, reaches its peak in mid-August, and floral display lasts over two months. \u2018Gold Standard\u2019, in fact the whole species exhibits excellent disease resistance, particularly powdery mildew, downy mildew, and leaf spot, that plague other coreopsis. \u2018Gold Standard\u2019 is a rhizomatous cultivar that spreads slowly\u2013 about 2\u2019 over three years.\n

  4. \u2018Last Dance\u2019 coreopsis<\/strong> (C<\/em>. integrifolia<\/em> \u2018Last Dance\u2019) is a fall-blooming tickseed that has a superior uniformly compact habit over other forms of\u00a0C. integrifolia<\/em>. \u2018Last Dance\u2019 emerges slowly\u00a0 in spring and does not reach 1 foot tall until June, and is just 2 feet tall.\u00a0The gold colored flowers are extra-large (2 inches) with thick pleated petals. It is the latest coreopsis to flower in October.<\/li>\n<\/ol>\n
