Accent Series Impatiens
Accent Series Impatiens are the reliable workhorses of summer color, delivering weeks of continuous blooms in a compact, mounding form that thrives in partial shade. These hybrid annuals reach just 8-10 inches tall and produce flowers in numerous colors, making them natural choices for porches, window sills, and shaded garden beds. They mature quickly, reaching full bloom potential in 70-79 days, and handle the summer heat better than many shade-loving plants.

Highlights
These dwarf impatiens grow into tidy mounds without constant fussing, staying neat and floriferous from early summer through frost. The Accent Series became the most popularly grown impatiens in American greenhouses and home gardens for good reason: they deliver consistent, abundant color in the shadiest corners where few other annuals perform. They show genuine resistance to Powdery Mildew, a common problem that stops many impatiens in their tracks during humid summers.
Common Uses
Accent Series Impatiens are grown purely for ornamental display. They excel in shaded borders, containers on covered porches, window boxes, and any partially shaded spot where you need reliable seasonal color without maintenance demands.

Care Instructions
Start Indoors
Start seeds indoors 8-10 weeks before your last spring frost. Scatter seeds on moist seed-starting mix without covering, as impatiens seeds need light to germinate. Keep soil temperature around 70-75°F and maintain consistent moisture. Seedlings typically emerge in 10-14 days. Thin or transplant seedlings once they develop their first true leaves.
Transplant Outdoors
Harden off seedlings by gradually exposing them to outdoor conditions over 7-10 days. Transplant after all danger of frost has passed and soil has warmed to at least 60°F. Bury the transplants at the same depth they were growing in their containers, spacing them 15 inches apart. Water gently after planting and keep soil moist for the first week.
Pruning
Pinch back the growing tips when seedlings are 2-3 inches tall to encourage a bushier, more compact mound. In mid-summer, if plants become leggy or sparse, cut back the top growth by about one-third to stimulate new branching and denser flowering.

History & Origin
“The Accent Series represents the modern breeding of Impatiens walleriana into forms specifically suited to container and landscape production. Developed for commercial greenhouses, these hybrids were selected for their dwarf, mounding habit and rapid maturation, bringing reliable summer color to growers across the country. The series became the undisputed standard for summertime impatiens production, passed from nursery to home gardener as the go-to choice for shade.”
