Papaver naudicale or the Iceland Poppy is a short lived, tuft-forming perennial usually treated as an annual.
It forms a tuft of greyish-green, pinnately divided leaves and the crinkly saucer-shaped flowers rise on long, hairy stems above. The individual blooms last for many weeks.
They may be white, yellow, pink, orange or red and make an delicate, yet colourful addition to any mixed border.
Iceland Poppies are an absolute must to include in any informal garden design, whether it be in borders or pots and planters. In fact I'd suggest any location (like window boxes) that has a good amount of sun, in order to enjoy these delightfully delicate and colourful flowers.
They make good cut flowers too, providing they are harvested just as the bud is opening.
