More About Geranium ‘Savannah® Blue’

Savannah® Blue stands out for its cool lavender-blue flower tones—an uncommon color range in zonal geraniums. The blooms bring a calming, refined presence to garden designs and pair especially well with whites, silvers, and soft pastels. Flower color remains stable throughout the season without washing out in sun or heat.

The plant maintains a dense, well-branched structure that fills in evenly in both containers and beds. Its upright habit keeps flowers visible and well-presented, making it a strong performer in mixed plantings and mass displays.

Why We Like It (Our Trials)

In our trials, Savannah® Blue consistently stood out for its ability to maintain cool, lavender-blue tones through periods of intense heat and strong sun—conditions where blue and purple shades often wash out or shift color. The blooms remained clean and evenly colored without fading, bronzing, or becoming muddy as the season progressed. Flower coverage stayed strong, with blooms held neatly above the foliage for clear visibility and balanced presentation.

Equally impressive was the plant’s structure. Savannah® Blue maintained a compact, symmetrical habit with excellent branching, showing no signs of stretching or uneven growth even during peak summer temperatures. We especially appreciate this variety for gardeners who want to introduce cooler, calming color into summer plantings without giving up durability or performance. It delivers the rare combination of refined color and dependable, heat-tough garden behavior.

Savannah® Blue vs. Other Geraniums

Savannah® Blue stands apart for its rare cool-toned lavender-blue coloration, a standout within a series dominated by warm and neutral hues. It brings calm, refined contrast while maintaining the same heat tolerance and compact habit as the rest of the Savannah® Lineup. The color remains stable through summer, which is uncommon for blue-toned geraniums.

When compared to Savannah® White, Blue feels softer and more atmospheric, adding depth rather than brightness. Against Savannah® Really Red and Oh So Orange, it provides a cooling counterbalance that prevents bold color combinations from feeling overwhelming. Compared to Savannah® Light Salmon, Blue reads cooler and more modern, while Lavender Splash offers pattern where Blue delivers uniform color. Gardeners choose it for cool color impact without giving up summer durability.
