Specific to this plantAl wrote these notes for this exact specimen. Where they differ from the Euphorbia guide, the plant in front of you is right.
A variegated Euphorbia obesa hybrid in a 3.5-inch pot — the rarest variegation pattern in the obesa lineage, where pale sectors thread through the body without compromising vigor. Smaller pups may break off in shipping; this is normal for the form and they often root readily.
Bright filtered light, slightly less than for green obesa. The variegated tissue burns more easily and the white sectors lack chlorophyll, so the plant overall is more sun-shy.
Waterthis plant
Sparse but consistent. Variegated plants run on slimmer photosynthetic margins; overwatering combined with their slower metabolism rots them faster than green stock.
Pure mineral mix favoring pumice and decomposed granite. A small terracotta pot with excellent drainage is the safest format for this material.
Dormancythis plant
Mild winter slowdown. The plant does not fully dormant but cuts metabolic rate sharply below 60°F; reduce watering accordingly.
Hardinessthis plant
USDA 10b–11 (50°F floor; variegated Euphorbias are less cold-tolerant than their green counterparts, add a margin).
Feedingthis plant
Quarter strength balanced fertilizer monthly during active growth. Heavy feeding can blur variegation patterns and produce reverted, pure-green pups.
Repottingthis plant
Every two years. Handle pups gently; the caustic latex is the same as in green Euphorbia obesa, and gloves and eye protection are required.
Watch forthis plant
Reversion to pure green in vigorous pups; remove green-only offsets to preserve the variegation in the parent body.
