Planting Schedule

Add Krinkled White to your garden to build a schedule and get reminders.

Soft as spun lace, Krinkled White opens in clouds of creamy white petals that hold their shape with a gentle, crumpled elegance.

The blooms are richly textured—layered, ruffled, and distinctly “krinkled”—with a luminous presence that turns the garden into a quiet, moonlit spectacle. Grow Krinkled White for long-lasting, showy garden peony color and a refined, romantic bloom habit that anchors borders and cottage beds for seasons to come.

Frequently Asked Questions

What pest or disease most commonly affects Paeonia lactiflora (Krinkled White peony), and what should I do if I see it?
Watch for botrytis (gray mold), especially when spring weather is cool and wet; it shows up as brown/gray lesions on shoots and buds. Cut and discard affected stems back to healthy tissue, improve airflow with spacing, and avoid overhead watering; after new growth appears, a labeled fungicide can be applied if disease pressure is high. Also remove fallen leaves in fall because botrytis can persist on plant debris.
How often should I water Paeonia lactiflora during the main growing phase, and what soil moisture level is best?
During active growth (spring through early summer), keep the root zone evenly moist but not soggy—aim for watering when the top 1–2 inches of soil dry out. Water deeply so moisture reaches the crown and deeper roots, then let the surface dry again to prevent rot and gray mold. In full sun sites, plan on more frequent deep watering during hot stretches, but never leave the peony sitting in water.
How can I tell when Krinkled White (Paeonia lactiflora) is ready to harvest?
Harvest for cut flowers when the bud is fully colored and just starting to loosen—petals should be visible but not fully opened. If you wait until the bloom is fully open, it won’t last as long in the vase. Cut early in the morning, and only take a few stems per plant so the remaining foliage can still support next year’s buds.

Expert Note

For peonies, plant the crown at the correct depth (about 1–2 in below soil in cooler regions) to avoid weak or no flowering.
