Many big-flowered poppy species varieties are often called pseudo-oriental poppy, but the true pseudo-oriental poppy is the biggest and largest-flowered ornamental poppy that grows in Finland. This beautiful-flowered plant has become very popular and has in many places marginalized the previously popular, almost same-sized oriental poppy (P. orientale). It is usually quite easy to differentiate between the species when you know what you’re looking for: pseudo-oriental poppy’s stem is leafy until the top, the bud is erect, the base of the flower petals usually have a clear dark blotch, and the capsule is oval, egg-shaped.
Pseudo-oriental poppy is a joy to the eye, but it has no medicinal properties. Like most species in the genus, pseudo-oriental poppy’s natural area of distribution is the temperate parts of the old world, and it is native to Turkey and Iran. In Finland it thrives best in sunny habitats on land that has very good drainage.
