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.

Euphorbia ‘Glacier Blue’ vs. Other Euphorbia

Compared to darker foliage selections like ‘Blackbird’, ‘Glacier Blue’ offers a lighter, cooler color palette with emphasis on bloom and brightness rather than depth. Both are excellent performers, but they serve very different design roles.

When compared to variegated types like ‘Ascot Rainbow’, ‘Glacier Blue’ provides a cleaner, more restrained look, ideal for gardeners who prefer subtle contrast over bold variegation. For those seeking a low-maintenance euphorbia with extended bloom and cool-toned elegance, Euphorbia ‘Glacier Blue’ is an excellent choice.
