Purple/Black Pepper Leaves: Hybrid Trait, Not Disease

Widespread 2024 Phenomenon

Many gardeners report purple/black stems/leaves on healthy, fruiting peppers. Likely anthocyanin expression in new hybrid lines—stress response or breeding artifact.

If Plants Thrive, Ignore Color

Check seed packet: "hybrid" or "F1"?
No wilting, spots, insects? → cosmetic only.
Reduce water slightly (test variable).
Monitor—report changes.

Open-Pollinated Alternative

Heirlooms (e.g., 'California Wonder' OP) show stable green foliage.
