Corn Poppy (Papaver rhoeas) - Key Growing Information

A single bloom of the common, lipstick-red Flanders (corn) poppy, atop its 3-foot-high, branching stems with downy leaves.

DAYS TO GERMINATION:

Allow 14–21 days at 60–75°F (16–24°C).

SOWING:

Sowing in place is recommended, as early as the soil can be worked. Cover seed very lightly, about 1/4" deep at most, and thin when true leaves form. Don't transplant: poppies have a delicate taproot and react badly to root disturbance.

LIGHT PREFERENCE:

Full sun.

PLANT HEIGHT:

Grows about 12–24" tall.

PLANT SPACING:

Space plants 6–8" apart.

HARDINESS ZONES:

Grown as an annual.

HARVEST:

Cut when buds are plump and showing color, and sear the stem ends. Expect 2–4 days in the vase.

SOIL REQUIREMENTS:

Any moist soil that drains well.

USES:

Naturalized plantings, massed displays, beds and borders. As a cut flower it is very short-lived.

SCIENTIFIC NAME:

Papaver rhoeas
