Coreopsis gandiflora 'Sunny Day'
This selection forms a bushy mound of green leaves, bearing upright stems loaded with large single golden-yellow daisies for many weeks, starting in early summer. Removing faded flowers regularly will encourage blooming to continue for weeks. This is a medium-sized selection that will not get overly tall or floppy and should not need to be staked. Tolerant of hot, humid summer climates. Excellent for borders, as well as in containers. Attractive to butterflies.
