Mysterious Bulb-Like Growths on Rose Stems

Not Seeds—Likely a Pest or Disease

Bulbous formations on rose stems (not rose hips) suggest a parasite, gall, or disease. Rose hips form at the base of spent flowers, not along stems.

Next Steps

• Describe structures in detail (color, texture, attachment).
• Consult rose specialist Lynette Payne (Allexperts Roses category).
• Photos would aid diagnosis.

Could be crown gall, mossy rose gall, or other pathology.
