Sarracenia flava Rust Spots: Benign Fungus on Nectar

Sarracenia flava Rust Spots: Benign Fungus on Nectar

Small black/red spots on pitchers after rain? Rust fungus feeding on dried nectar. Cosmetic only—doesn't harm the plant. Common on S. flava in heat.

Management

• Weekly sulfur fungicide may prevent, but washes off.
• Spots are permanent on affected leaves.
• New pitchers emerge clean until they age.

Unsightly but harmless. Focus on culture, not cosmetics.
