Easily grown in dry to medium moisture, well-drained soils in full sun. Tolerant of heat, humidity and some drought. Plants may be sheared in mid to late summer to promote a fall rebloom and to remove any sprawling or unkempt foliage. Plants may spread by rhizomes. Clumps may be divided in spring. When grown in borders or other formal garden areas, division may be needed every 2-3 years to maintain robustness.
Red Satin’ was bred by hybridizer Darrell Probst and is the first member of the Permathread™ series. It has 1 ½ in. wide, ruby to wine red ray flowers with gold disc flowers that will keep their color and rebloom all summer if cut back. ‘Red Satin’ grows 1 to 1.5 ft. tall and 1.5 to 2 ft. wide and has dark green, thread-leaf foliage. It is hardier than other red flowered Coreopsis and since its flowers are sterile, will not self-seed. U. S. Plant Patent Applied For (PPAF).
