The foliage is feathery and grows from fuzzy, leafless flower stems.
Poppy flowers are brightly colored with four paper-thin, silky, and ruffled petals.

Plant seeds in their permanent outdoor space in late winter or early spring.
Like other poppies, Iceland poppies contain alkaloids that are toxic to humans and animals.
These perennials are also excellentdeer-resistantplants.

They can be grown in partial shade, too, if necessary.
Soil
Iceland poppies need rich, well-draining soil.
Create a consistent watering schedule, and ensure you’re not drowning them when doing so.

Water close to the soil.
Temperature and Humidity
Iceland poppies are hardy plants and enjoy cooler temperatures.
The only exception is when you start Iceland poppies from seed.

To germinate, the seeds prefer a slightly warmer and moist climate.
Fertilizer
Iceland poppies thrive from a consistent and frequent fertilizing schedule.
Use a well-rounded,balanced fertilizer, such as 20-20-20, to give your plants the nutrients they need.
How often you fertilize depends on the soil.
If you have rich soil, you may only need to fertilize once or twice per growing season.
Otherwise, your poppies will appreciate consistent food; aim for every other week or so.
This will encourage your poppies to produce more flowers.
Harvest Seeds
Harvesting seeds is all the same for both methods.
If planted in the fall, they will stay dormant throughout the winter.
For early spring planting, sow seeds as soon as the ground is workable for the same results.
Container Method
Iceland poppy seeds need tender loving care when sowing in containers.
They require a warm environment for germination.
A rough transplant can easily kill poppies.
Take care not to damage the root system when transferring poppies from their growing container to a garden.
One workaround for this delicate plant is to sow seeds in biodegradable nursery pots.
This way, the pot can go directly into the ground without having any roots disturbed.
Use fungicide and trim away weathered parts of the plant.
New blooms will stop in hot and humid conditions.
What Do Iceland Poppies Look and Smell Like?
Iceland poppies have large cup-shaped flowers with delicate, papery petals.
The blooms can be up to 4 inches wide.
How to Encourage More Blooms
Encourage more blooms by deadheading Iceland poppies' spent flowers.
Iceland poppies also prefer cool spring weather with temperatures around 70 degrees Fahrenheit or below to thrive and bloom.
Watch out for these issues.
Curled Leaves
Powdery mildew grow in humid conditions with poor air circulation.
Leaves will have white or gray fungal growth and may curl.
Space out plantings, remove affected areas, and apply a fungicide.
Root Rot
Overwatering and poor drainage can lead to root rot.
Ensure the soil is well-draining and water plants consistently without overwatering.
Iceland poppies are short-lived perennials that prefer cool weather, they are treated as annuals in warmer climates.
Iceland poppies are known to self-seed, especially when the weather and growing conditions are optimal.
They are not considered invasive though, and unwanted seedlings can be easily pulled up and removed.
double-check the plants are consistently watered and fed.
