Spurge Unveiled: The 6 Best Euphorbia Varieties for Every Garden
Resilient border plants deliver evergreen form and seasonal pops of bright color.
The secret to lasting structure, color, and resilience in mixed garden borders often comes down to a single, versatile genus: Euphorbia, commonly known as spurge. With more than 2,000 species ranging from sculptural succulents to lush flowering perennials, Euphorbia is the quiet workhorse of thoughtful garden design. Unfurling new growth in early spring, weathering winter with evergreen poise, and self-seeding with abandon, spurges add drama and reliability where it’s most needed.
Let’s explore six must-have varieties and see how to select, place, and care for them in any temperate garden.
Why Choose Spurges (Euphorbia)?
- Architectural interest in all seasons with bold forms, colorful bracts, and fascinating foliage
- Evergreen foliage in many cultivars that keep your borders lively year-round
- Self-seeding nature ensures a continuous display and plants adapting to their ideal spot
- Drought and deer resistance makes them tough choices for challenging sites
The Allure of Euphorbia
The horticultural name Euphorbia recalls the word Euphoric, an apt association for the cheerful, vibrant presence these plants bring at the dawn of the gardening season. Evergreen varieties form a dramatic backdrop even in winter, while deciduous types explode with neon-bright bracts in spring. From Mediterranean borders to modern gravel gardens, spurges have won pride of place in gardens of all styles.
Yet, not all spurges are bulletproof: some are tender and may succumb to hard frosts. However, thanks to their profuse self-seeding, lost specimens are swiftly replaced by a new generation, often selecting more favorable microclimates than you might have planned.
Ready to add Euphorbias distinctive flair to your planting schemes? Here are the six best varieties for both novice and experienced gardeners.
Six Best Varieties of Euphorbia (Spurge)
Euphorbia characias subsp. wulfenii
Key Features:
- Zones: 610 (hardier in sheltered spots)
- Structure: Upright, branching stems, 35 feet tall
- Foliage: Blue-green, tight whorls along stems; evergreen
- Flowers: Dramatic lime-green bracts from late winter through early summer
- Design use: Striking architectural centerpiece or background plant in contemporary or Mediterranean schemes
Among the most iconic spurges, E. characias subsp. wulfenii boasts bold, dense columns of foliage and is crowned with luminous chartreuse flower heads. In landscape designer Beth Chattos famed gardens, it features front and center, both as a specimen splayed against walls and paired serendipitously with espaliered buddlejas.
For added vibrancy, choose cultivars such as John Tomlinson or Lambrook Gold. Prune spent stems after flowering to encourage fresh growth and prevent excessive self-seeding. In harsh winters, plants may become leggy or suffer dieback, but seedlings often secure healthier, better-positioned replacements.
Euphorbia myrsinites
Key Features:
- Zones: 59
- Structure: Low-growing, trailing mat, 512 inches high
- Foliage: Spiraling, fleshy blue-gray leaves; evergreen
- Flowers: Yellow-green bracts in spring
- Design use: Border ground cover, container edge, gravel gardens
E. myrsinites, or myrtle spurge, forms striking rosettes of chalky blue leaves that twist along sprawling stems. Its an ideal choice for tumbling over walls, softening paving edges, or filling rocky gaps. This variety is famously drought-tolerant and thrives in poor, fast-draining soils.
Its mat-like habit makes it a weed-suppressing ground cover, while bright yellow flowers provide a springtime lift. Take care: in certain U.S. states its considered invasive due to prolific self-seeding. Remove flowering stems after blooming to keep it tidy and to prevent unwanted spread.
Euphorbia robbiae (Mrs Robbs Bonnet)
Key Features:
- Zones: 69
- Structure: Spread by rhizomes, to 18 inches high
- Foliage: Glossy, deep green, rosette-forming, evergreen
- Flowers: Yellow-green bracts in early to mid-spring
- Design use: Excellent ground cover, under trees, dry shade
Sometimes called wood spurge, E. robbiae is unrivaled in dry shade. Its bold foliage carpets tricky corners beneath trees where little else can thrive. The softly spreading mats will gradually cover bare soil, impeding weeds and brightening the gloom with cheerful, green-tinted flowers early in the year.
This resilient perennial will easily settle in neglected alleys or beneath mature shrubs. It can suppress less aggressive companions, so pair thoughtfully and thin as needed.
Euphorbia polychroma (Cushion Spurge)
Key Features:
- Zones: 49
- Structure: Compact domes, 1218 inches tall
- Foliage: Fresh green, oval leaves, turns orange-red in fall
- Flowers: Sulphur-yellow bracts
- Design use: Edging, cottage gardens, spring color statements
Creating dense cushions of color, E. polychroma is a favorite for spring displays. Its domed, tidy shape lends structure to borders, while an eruption of vivid yellow bracts in mid to late spring floods garden beds with light. As seasons change, foliage takes on russet-orange tints, carrying visual interest into autumn.
Grow it in sun to part shade. Cut back faded flower stems to maintain neatness and shape. Pair it with late-flowering bulbs or low grasses for textural contrast.
Euphorbia Ascot Rainbow
Key Features:
- Zones: 69
- Structure: Upright, bushy form, to 20 inches
- Foliage: Variegated green, gold, and cream with red tips in cool seasons
- Flowers: Chartreuse with red-pink accents
- Design use: Contemporary schemes, mixed containers
The vibrantly variegated foliage of Euphorbia ‘Ascot Rainbow’ glows with cream, gold, and subtle green throughout the year, while cool weather brings striking red tips. Its upright habit makes it uniquely suited for containers or prominent garden positions, where its foliage is a standout feature.
Blooms in spring develop soft red-pink tones, echoing the vermilion highlights in its leaves. Trim after flowering for a compact, bushy effect and let new growth shine through.
Euphorbia rigida
Key Features:
- Zones: 710
- Structure: Upright, bold perennials up to 2 feet
- Foliage: Blue-gray, succulent leaves arrayed along strong stems
- Flowers: Early, bright green-yellow bracts starting as early as February
- Design use: Mediterranean borders, xeriscaping, modern planting plans
Like a larger, bolder version of E. myrsinites, Euphorbia rigida delivers architectural drama. Its evergreen blue-gray leaves spiral neatly along firm stems, and the entire plant flares with luminous yellow bracts in late winter and springa beacon against bleak landscapes.
Ideal for exposed sites, sunny slopes, or dry gravel gardens, E. rigida shrugs off drought, resists browsing deer, and maintains a striking silhouette even in the off season.
Designing & Caring for Spurges
Spurge is as valuable for structure as it is for color, making it a mainstay in modern gardens, classic borders, and even urban containers. Here are a few essential tips:
- Soil & Light: Most Euphorbia thrive in well-drained soil and full sun, but many tolerate part shade, especially E. robbiae.
- Pruning: Cut flowered stems to the ground after blooming to refresh foliage and encourage compact growth.
- Safety: The milky white sap can be a skin irritant; wear gloves when handling.
- Self-seeding: Let seedlings stay where they thrive or edit freely to maintain balance.
- Pairing: Use with ornamental grasses, bulbs, roses, and silvery Mediterranean perennials for contrast and extended interest.

Frequently Asked Questions (FAQs)
Q: Are spurges toxic?
A: Yes; Euphorbia species exude a white, milky sap that can be a serious skin and eye irritant and is toxic if ingested. Always wear gloves and keep children and pets away from cut stems.
Q: How and when should I prune euphorbias?
A: Prune after flowering by cutting spent flower stems down to the base. This encourages new shoots and keeps plants tidy; wear gloves and rinse tools afterward.
Q: Can spurges cope with dry soil or drought?
A: Absolutely. Many spurges, especially from Mediterranean or steppe origins (like E. rigida, E. myrsinites), excel in dry, well-draining soil and require minimal extra water once established.
Q: Will spurge spread in my garden?
A: Both! Spurges are known for vigorous self-seeding and spreading by rhizomes (particularly E. robbiae). Thin unwanted seedlings or runners to control spread.
Q: What can I grow with spurges?
A: Spurges combine beautifully with roses, ornamental grasses, bulbs (such as alliums or camassias), and Mediterranean perennials like lavender, salvia, and cistus for contrast and extended flowering interest.
