Why We Like It (Our Trials)

In our trials, Savannah® Oh So Orange stood out for its heat tolerance, stem strength, and consistent flowering during peak summer conditions. While many orange-toned geraniums can lose vibrancy or structure in extreme heat, this variety held its color and form exceptionally well.

We especially like it for gardeners looking to introduce bold, warm color without sacrificing durability or polish. Whether used as a focal point in containers or planted in repeating drifts throughout the landscape, Savannah® Oh So Orange delivers dependable performance with standout visual impact.

Savannah® Oh So Orange vs. Other Geraniums

Savannah® Oh So Orange stands out in the Savannah® Series for its unmatched warmth and visual energy. Among the lineup, it delivers the most saturated orange tone, creating instant impact without reading harsh or artificial. The color stays bold even in peak summer heat, and the plant maintains the same tight, well-branched structure that defines the series, making it a high-impact option that still feels controlled and intentional.

Compared to Savannah® Light Salmon, Oh So Orange is noticeably more intense and energetic, leaning vibrant rather than soft. Against Savannah® Really Red, it feels warmer and more playful, while Really Red carries a more traditional, classic presence. When paired with Savannah® White or Savannah® Blue, Oh So Orange becomes a focal point, anchoring cooler tones with heat and brightness. Compared to Savannah® Lavender Splash, it offers solid, uniform color rather than pattern-driven interest. Gardeners love it for bold summer color that doesn’t sacrifice structure or performance.
