Sun Harmony™ White Impatiens hybrida

[Sun Harmony™ White](https://www.rhs.org.uk/plants/361839/impatiens-sun-harmony-white-sun-harmony-series-ng/details) is the white-flowered trade selection in Danziger’s Sun Harmony series of New Guinea impatiens. It forms a compact, well-branched mound with large white blooms through summer ([Premier Growers](https://premiergrowersinc.com/product/new-guinea-impatiens-sun-harmony-white/)). A grower listing reports a height and spread of 16–20 inches. ## Flowers and form The Royal Horticultural Society classifies the exact name as a trade name and describes New Guinea impatiens as a horticultural group derived from *Impatiens × hawkeri*. An industry report covering Danziger’s introductions identifies Sun Harmony White as the series’ white color, with large flowers and good garden performance ([Greenhouse Grower](https://www.greenhousegrower.com/crops/danziger-highlights-the-best-of-its-2016-new-variety-introductions/)). ## Site and use Use it in a container or garden planting with full sun to partial shade. A product listing for the exact selection names full sun, partial sun, and partial shade; the trial report describes the series performing from full sun to part shade and tolerating high and low temperatures. Allow about 16–20 inches for the compact mound; it suits grouped seasonal displays as well as container plantings. ## Maintenance Check containers and bed plantings during summer and remove damaged stems or spent flowers as they occur to keep the compact mound tidy.
