The Yellow Iceland Poppy (Papaver nudicaule) is a delicate, herbaceous perennial often grown as an annual in cooler climates. It boasts papery, cup-shaped flowers in a luminous yellow hue, perched atop slender, leafless stems that rise gracefully from a low mound of finely dissected, blue-green foliage. The blooms have a satiny texture and a slightly crinkled appearance, adding a soft, ethereal quality to the garden. Each flower opens in succession, offering a prolonged display of color through spring and early summer.
