Euphorbia Fireglow
Euphorbia 'Griffithii', Fireglow Spurge
Euphorbia 'Fireglow' is a striking perennial that brings bold colour and structure to the garden. Known for its vibrant orange-red stems, blue-green foliage and glowing red-orange bracts in spring and early summer, this eye-catching Euphorbia creates a dramatic display that stands out in borders, cottage gardens and Mediterranean-style plantings.
As temperatures cool in autumn, the foliage often develops rich red and bronze tones, extending its season of interest. Tough, drought tolerant and easy to grow, Euphorbia Fireglow is an excellent choice for gardeners looking for colour, texture and year-round garden performance.
Please note: Like all Euphorbias, Fireglow produces a milky sap that can irritate skin and eyes. Wear gloves when pruning or handling.

How to maintain your Euphorbia Fireglow once established?
How to maintain your Euphorbia Fireglow once established?
Euphorbia Fireglow thrives in:
Well-drained garden soil
Sandy or loamy soils
Raised beds
Cottage garden borders
Avoid sites that remain wet during winter.
Good drainage is essential for healthy long-term growth.
Water regularly while establishing.
Once established, Euphorbia Fireglow becomes relatively drought tolerant and usually only requires watering during extended dry periods.
Avoid overwatering, particularly in winter.
Feed lightly in spring with:
Compost or well-rotted organic matter
General-purpose slow-release fertiliser
Heavy feeding is generally unnecessary and can encourage excessive soft growth.
After Flowering
Flowering stems should be removed once blooms have faded.
Cut spent flowering stems back to the base, allowing fresh shoots to develop for the following season.
General Maintenance
Remove damaged or untidy stems as needed.
Wear gloves when pruning due to the irritating milky sap.
Wash hands thoroughly after handling.
Managing Spread
Euphorbia Fireglow can slowly spread by underground rhizomes in ideal conditions.
If necessary:
Lift and divide clumps every few years.
Remove unwanted shoots that appear beyond the desired planting area.
Fireglow is generally frost hardy throughout most of New Zealand.
For best results:
Ensure good winter drainage.
Leave foliage in place until late winter if desired.
Remove old stems before fresh spring growth begins.
Dividing Plants
Mature clumps can be divided every few years during autumn or early spring.
Division helps maintain vigour and provides additional plants for other areas of the garden.
Euphorbia Fireglow combines beautifully with:
Verbena bonariensis
Salvia Amistad
Salvia leucantha
Gaura So White
Echinacea
Nepeta
Ornamental grasses
The fiery orange-red tones provide a stunning contrast against purple, blue and white flowering plants.
