More About New Guinea Impatiens Petticoat® ‘White Wonder’

New Guinea Impatiens Petticoat® ‘White Wonder’ is prized for its large, frilled pure-white blooms that bring brightness and elegance to shaded gardens and containers. The softly ruffled petals create a layered, almost fabric-like appearance, giving this variety a refined, high-end look compared to standard impatiens. The blooms are displayed above lush, glossy green foliage, providing clean contrast and excellent visibility even in deep shade. The crisp white color makes this variety especially useful as a unifying element in mixed plantings.

Why We Like It (Our Trials)

In our trials, ‘White Wonder’ has been uniform, vigorous, and consistently floriferous throughout the growing season. It fills containers evenly, maintains clean foliage, and continues blooming steadily through summer heat when moisture is consistent. We especially appreciate its design flexibility. White is one of the most valuable colors in shade plantings, and the ruffled Petticoat® blooms elevate this variety from simple filler to true focal plant when needed.

Petticoat® ‘White Wonder’ vs. Dark-Foliage Varieties

‘White Wonder’ is the brightest and cleanest option in the Petticoat® Series, using crisp white blooms to maximize contrast against the dark foliage. Compared to Dark Red and Red Star, it feels lighter and more elegant, particularly in shaded spaces where white flowers help illuminate darker corners. The white blooms also highlight the foliage itself, making the dark leaves part of the visual feature rather than just a backdrop.

Against Sonic® varieties, ‘White Wonder’ offers stronger contrast but slightly less overall color saturation. It shines in refined containers, formal shade gardens, and combinations where balance is more important than intensity. Petticoat® ‘White Wonder’ is a natural fit for brightening shaded spaces while keeping plantings refined and visually clean.
