Impatiens walleriana 'Accent'
Impatiens walleriana ‘Accent’ is a long‑standing bedding series valued for large blooms and vigorous plants. It forms rounded mounds that flower steadily from late spring to frost. Plants suit packs, containers, and mass plantings in shade. This line is commonly grown as a warm‑season annual across North America. It is part of the Goldsmith breeding legacy now under Syngenta Flowers.
