Planting & Care Guide

Ideal Location

Plant ‘Sunsation’® in a site that receives at least six hours of direct sunlight daily to maximize foliage color. It tolerates partial shade but may develop greener leaves when light levels are low. Ensure the location has well-drained soil to prevent root rot.
