Its measured trial size was 15 inches tall by 23 inches wide; allow room for the plant to spread, especially near the front of a bed or at the edge of a container.

The Mississippi State trial lists this exact selection as a sun annual, while Penn State evaluated it in a sun container planting. Use it where its warm flowers and spreading outline can soften a container edge or fill a sunny seasonal display.

The cited trial sources do not specify a universal soil recipe or watering schedule, so adjust care to local conditions and the container or bed. Remove damaged growth as needed and replace the plant after the season in climates where it does not survive winter.
