Reina™ Single Giant Gold - Coreopsis

Reina™ Single ‘Giant Gold’ is a distinct Coreopsis selection, separate from Reina Gold. In Penn State’s [2023 sun-ground trial](https://agsci.psu.edu/flower-trials/trial-year/2023/plant-name/coreopsis-reina-single-giant-gold), it received a 4.75 average from 12 ratings, with yellow flowers; the trial recorded plants 17 inches tall and 24 inches wide. Those are observations from one site and season, not a guaranteed mature-size specification. Use the trial as evidence of its performance in a sunny landscape planting, while allowing for differences in climate and culture. The available grower listing also presents Giant Gold separately within the Reina range; do not substitute measurements or characteristics from another Reina cultivar. General Coreopsis guidance favors a sunny, well-drained site, but the opened selection-specific sources do not establish a hardiness range or a fixed garden-size range. ## Maintenance Plant in sun and well-drained soil. Water during establishment and prolonged dry weather. Remove spent flower heads as desired to keep the planting tidy.
