Plant : Spurge
Euphorbia spp.
Spurge is a large and diverse genus of plants known for its architectural form, striking foliage, and long-lasting greenish-yellow bracts that resemble flowers. These resilient perennials thrive in poor, dry soil and offer unique texture and color to rock gardens, borders, and low-maintenance planting schemes. Some species have seasonal color changes, while others flower through winter and early spring.

Care Instructions:
Euphorbias range from dwarf trailing varieties like E. myrsinites to statuesque types such as E. characias subsp. wulfenii, reaching 2 meters tall. With blue-green foliage and eye-catching bracts, spurges bring both structure and brightness to sunny gardens. Though most prefer dry, well-drained soil, species like E. palustris and E. sikkimensis are suited for moist spots. The milky sap of all Euphorbia species is toxic and may cause skin irritation—gloves should always be worn when handling. These drought-tolerant plants self-seed freely, making them ideal for naturalistic or low-care gardens.
Light
Most spurges do best in full sun but can also tolerate partial shade. Shadier spots work well for varieties like E. amygdaloides var. robbiae.
Water
Water only during prolonged dry spells. Once established, most spurges thrive with minimal irrigation. Avoid overwatering.
Soil
Well-drained, poor soil is preferred. Chalky or sandy soils are ideal. Moisture-loving species (like E. palustris) are exceptions and need richer, damp soil.
Temperature
Hardy in temperate climates, but protect from severe frost. Some species flower as early as January.
Humidity
Tolerates dry air; avoid damp, stagnant conditions that encourage mould or rot.
Fertilizer
Avoid high-nutrient feeding. Too much fertilizer may reduce flowering and make plants leggy. Top dress with compost in spring if needed.
Best Placement Ideas
- Dry sunny borders or slopes
- Rock gardens or alpine beds
- South-facing walls or containers
- Woodland edge with shade-tolerant types
- Naturalistic or drought-tolerant designs
Common Issues
- Grey mould in cold, wet conditions
- Sap irritation during handling
- Overcrowding may inhibit airflow
- Weak stems in over-fertile soil
Things to Watch Out For
- Toxic sap: wear gloves when cutting or propagating
- Not all species tolerate transplanting (E. characias dislikes root disturbance)
- Self-seeding can become excessive
- Some annuals fade quickly in wet summers
Propagation Tips
Sow seeds in spring in well-drained compost. Transplant seedlings when large enough. Take 8 cm stem cuttings in May and root in sandy mix. Do not divide species that resent root disturbance.
Maintenance Tips
Cut back flowering stems after bloom to encourage bushy regrowth. Remove self-sown seedlings in spring or autumn and replant as desired. Provide wind protection for delicate species
Did You Know?
Despite their floral appearance, the “flowers” of spurges are actually modified leaves called bracts—the true flowers are tiny and often inconspicuous.
