WILDLIFE & INSECTS
Bees
- Nectar and pollen source for solitary bees, bumblebees, and small sweat bees early in the growing season.
Butterflies
- Occasionally visited by early season butterflies including Spring Azures and Pearl Crescents.
Moths
- Foliage provides low cover and early nectar for day flying moths such as Chickweed Geometer.
Beneficial Insects
- Supports hoverflies and parasitic wasps helping maintain ecological balance in low input gardens.
Spacing & Landscape Use
Spacing Recommendations:
- Space 18 - 24 in apart for maximum foliage contrast and to reduce crowding in sunny borders.
Landscape Placement:
- Ideal for compact rock gardens, xeriscapes, and raised beds where striking foliage and low upkeep are key design elements.
Companion Plants
- Allium schoenoprasum (Chives) - Adds upright purple blooms that rise above Euphorbia’s low mounds and echo the yellow bracts.
- Coreopsis verticillata 'Zagreb' (Threadleaf Coreopsis) - Offers bright golden blooms and feathery foliage for fine textured contrast.
- Festuca glauca 'Elijah Blue' (Blue Fescue) - Echoes the compact mound and adds icy color contrast to Bonfire’s fiery tones.
- Salvia nemorosa 'Caradonna' (Wood Sage) - Sends up deep violet spikes that rise cleanly above Euphorbia’s domed foliage.
- Stachys byzantina (Lambs Ear) - Provides tactile silver foliage that softens plantings and contrasts with Euphorbia’s bracts.
