More About Euphorbia ‘Glacier Blue’

Euphorbia ‘Glacier Blue’ is prized for its cool-toned blue-green foliage and luminous pale bracts that give the plant a fresh, refined look from late spring into summer. The soft white to icy-blue flower bracts hover above the foliage, adding brightness without overpowering surrounding plants.

This variety maintains a tidy, upright habit and delivers a much longer bloom window than many traditional euphorbias. Even after peak bloom, the foliage continues to provide clean structure and color contrast in the garden.

Why We Like It (Our Trials)

In our trials, ‘Glacier Blue’ has been extremely dependable in full sun to partial shade. It handles heat, drought, and variable soil conditions with ease, maintaining strong color and form with very little maintenance.

We especially appreciate how versatile it is in design. The cool color palette pairs beautifully with purples, silvers, whites, and dark foliage plants, making it easy to use in both modern and classic garden styles. Deer consistently avoid it.

Glacier Blue vs. Other Euphorbia Varieties

Glacier Blue is the most subtle and calming Euphorbia in the collection, prized for its cool blue-green foliage and soft chartreuse spring bracts. It blends naturally into borders rather than demanding attention, making it ideal for cottage gardens and layered plantings. The foliage maintains a refined, understated look throughout the season, providing structure without visual noise.

Compared to Tasmanian Tiger Euphorbia, Glacier Blue is quieter and more harmonious, offering balance instead of contrast. Against Ascot Rainbow and Bonfire, it feels restrained and soothing, helping to unify more colorful plantings. When placed next to Blackbird, Glacier Blue acts as a cooling counterpoint to dark intensity. Unlike Diamond Frost, it contributes calm structure rather than airy bloom. Gardeners choose Glacier Blue for its soothing color and ability to tie diverse plantings together.
