Oreomecon radicata is a small, cold-hardy Arctic and alpine poppy with white or yellow cup-shaped flowers, grown mainly in cold regions. Its key is cold, well-drained gravelly soil and full sun.
Family
Papaveraceae (Poppy family)
Light
Full sun
Water
Water moderately during the growing season and let the soil drain freely, avoiding waterlogging.
Soil
Gritty, rocky, well-drained mix such as sand and gravel with a little organic matter.
Temperature
Tolerates cold well; suited to cool summers and very cold winters, protect from heat above about 25 °C.
How easy
Hard
Safety
Toxic: Contains alkaloids throughout the stem, leaves and flowers that can affect the central nervous system if eaten.
About
The Arctic poppy (Oreomecon radicata) is a flowering plant in the poppy family. It may also be referred to as rooted poppy or yellow poppy. Arctic poppies grow in cold climate conditions and are found in Arctic regions of Europe. The Arctic poppy has many adaptations, such as heliotropism and physical characteristics, which help them survive in the harsh environment they grow in.
Safety
Arctic poppies contain alkaloids throughout the entirety of the flower structure, from the stem to the leaves. These alkaloids protect and assist the survival of the Arctic poppy in a number of ways. When Arctic poppies are consumed, the alkaloids within the poppy can affect the central nervous system, protein synthesis, enzyme activity, and membrane transport of the predator. Because of these effects, the Arctic poppy is not a direct food source for many species. Alkaloids are known to act as a growth regulator and can aid in the plant's reproduction rates. Alkaloids can even act as herbicides, which inhibit the growth of competing plants. They also act as substitutes for important minerals, like calcium and potassium, that can be difficult for the Arctic poppies to receive in their environment.
Where it grows
The Arctic poppy grows primarily in gravelly, rocky, well-drained soils, but can also grow in meadows. The poppies are circumpolar in distribution, and are found in Arctic and alpine zones within Europe, North America and Asia. In 2023, the Arctic poppy was the northernmost flowering plant in the world, with a northern range limit on Kaffeklubben Island at a latitude of 83°40'N.
