Care Guide for Euphorbia abyssinica var. erythraeae variegata
 → Light and Placement

  
Place in a south-facing window or under grow lights for at least 6–8 hours daily.
  
Rotate occasionally to maintain symmetrical growth.


 → Watering

  
Allow soil to dry out completely between waterings.

Interesting Facts

  
Unlike many succulents, this variety rarely produces leaves — energy is focused on thick, chlorophyll-rich stems.
  
Variegation is the result of a genetic mutation that reduces pigment production. It does not guarantee stability or permanence.
