Impatiens 'SunPatiens'
SunPatiens are interspecific impatiens bred for reliable performance in full sun and heat. Plants flower from spring to frost and keep a dense, mounded shape. Series options include Compact, Spreading, and Vigorous forms for beds and containers. They are widely used across North America as warm‑season annuals. The line was developed by Sakata Seed in cooperation with Indonesia’s IAARD using native germplasm. A SunPatiens selection earned a national All‑America Selections award for garden performance.
