Coreopsis 'Ruby Frost'

Ruby Frost is a hybrid tickseed with deep ruby-red to red-purple, daisy-shaped flowers edged in white, green foliage, and a dense, mounding habit. [Terra Nova](https://www.terranovanurseries.com/product/coreopsis-ruby-frost/) lists 16 inches for plant height, 32 inches for width, and 26 inches for flowering height; the final height reflects the flower stems rising above the foliage. The same grower lists zones 6–10, full sun, and bloom from June through September. The [plant patent](https://patents.google.com/patent/USPP21758P2/en) also describes a full-sun specimen with white-edged red-purple flowers and summer bloom, while noting that plant form varies with growing conditions. Its measurements reflect a particular trial specimen, so the grower’s separate foliage and flowering-height figures are useful when planning space. Leave room for the broad mound and place it where the contrasting flower edge is visible. ## Maintenance Grow in full sun and well-drained soil. Water during establishment and extended dry periods. Remove spent blooms to maintain a neat display; expect seasonal growth and flowering dimensions to vary with local conditions.
