WILDLIFE & INSECTS

Bees

  • Highly attractive to mining bees, sweat bees, and early visiting bumblebees during its prolonged spring bloom.

Butterflies

  • Draws in small butterflies like Eastern Tailed Blues and Spring Azures that seek sunny open garden forage early in the season.

Beneficial Insects

  • Bracts and stems provide habitat for hoverflies and tiny parasitic wasps which help control aphids and soft bodied pests.

Spacing & Landscape Use

Spacing Recommendations:

  • Space 18 - 24 in apart to allow room for its mounded form to develop without crowding.

Landscape Placement:

  • Excellent for rock gardens, dry borders, or at the front of perennial beds where spring color and textural contrast are desired.

Companion Plants

  • Achillea millefolium (Common Yarrow) - Matches Euphorbia’s drought tolerance and contrasts in flower shape and height.
  • Allium schoenoprasum (Chives) - Provides upright, edible foliage and spherical lavender flowers that complement Euphorbia’s domes.
  • Festuca glauca 'Elijah Blue' (Blue Fescue) - Offers spiky blue foliage in a compact form, echoing Euphorbia’s symmetry.
  • Geranium sanguineum (Bloody Cranesbill) - Forms loose mounds of deeply cut leaves and magenta flowers to extend the color season.
  • Stachys byzantina (Lambs Ear) - Brings soft silver leaves and a fuzzy contrast to Euphorbia’s vivid texture.
