How to grow oriental poppy

When to plant oriental poppy

Oriental poppy is propagated by seed or root cuttings and needs an adequate cold winter period for good germination (NC State). It generally struggles in heat and humidity south of zone 7; the foliage dies back after the early-summer bloom and a basal rosette reappears in fall.

Oriental Poppy is timed by season rather than your frost dates, so the planting calendar does not generate ZIP-specific dates for it. Check the cited sources below to fine-tune for your area.
