Papaver nudicaule
Iceland Poppy
Papaver nudicaule
Iceland poppies are short-lived perennials (often grown as annuals) known for their delicate, silky petals in a wide array of colors, from white and yellow to orange, red, and pink. They have a cup-shaped flower and hairy, bluish-green foliage. They prefer full sun and well-drained soil. They are relatively low-maintenance and easy to grow from seed.

Cultivars

Salvia officinalis
garden sage
Salvia officinalis
Sage's strong scent can deter some pests that might affect Iceland poppies, and the two plants have different growth habits, minimizing competition for resources.
Thymus vulgaris
common thyme
Thymus vulgaris
Thyme, like sage, has a strong fragrance that can deter some pests, and it also has a low, spreading growth habit that complements the taller Iceland poppy.
Delphinium elatum
Alpine Larkspur
Delphinium elatum

Delphiniums are tall and vigorous growers that can easily outcompete Iceland poppies for water and nutrients, particularly in areas with less-than-ideal soil conditions.

Digitalis purpurea
purple foxglove
Digitalis purpurea

Foxgloves also have a similar need for moisture and nutrients which will lead to direct competition with Iceland poppies for resources.

Aphids

Small, soft-bodied insects that suck sap from the plant, causing stunted growth and leaf curling. They can also transmit viruses.

Slugs and Snails

These mollusks feed on the leaves and stems, leaving holes and slime trails. They are particularly problematic in damp conditions.

Steps:

    • Sow seeds directly outdoors in spring or fall.
    • Prepare well-drained soil.
    • Plant seeds about 1/4 inch deep and space them appropriately.
    • Keep the soil moist but not waterlogged.
    • Thin seedlings to the desired spacing once they have a few true leaves.
    • Provide plenty of sunlight.

Neem oil

Effective against aphids and other sucking insects.

Diatomaceous earth

Helps control slugs and snails.
