Care & Maintenance
Pruning:
Cut back spent flower stems after flowering to maintain a tidy clump.

Minimal once established; avoid overwatering or damp, heavy soils.
Feeding:
Generally unnecessary; too much fertiliser reduces its natural colour intensity.

Typically pest-free; root rot may occur in poorly drained soils.
Additional Tips
Wear gloves when handling—like all Euphorbias, it produces a milky sap that can irritate skin. Plant in full sun for the strongest blue foliage tones.
