Troubleshooting
Lauren's Grape peony poppy problems — and how to fix them
Lauren's Grape peony poppy (Papaver somniferum 'Lauren's Grape') is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Stem lodging and breakage
The very large flower heads of this cultivar make stems especially vulnerable to wind and rain damage at 90–120 cm. Stake with bamboo canes or grow in a sheltered but well-ventilated spot. Avoid nitrogen-rich feeding which makes stems soft.
Downy mildew (Peronospora arborescens)
Systemic mildew causes pale upper-leaf mottling and a grey fuzz on undersides during cool, damp springs. Remove and destroy affected leaves promptly; do not compost. Improve air circulation and water at the base only.
Failure to true-breed from saved seed
Lauren's Grape does not breed fully true from saved seed — offspring may vary in double-ness, colour intensity, and petal number. For consistent results, source fresh seed from a specialist each season or hand-isolate the best plants from cross-pollination.
