15 Seeds Argemone polyanthemos Prickly Poppy Native Wildflower Drought Tolerant

Argemone polyanthemos, commonly called prickly poppy, is a striking native wildflower known for its large, papery white blooms and blue-green, thistle-like foliage. This drought-tolerant annual or short-lived perennial brings a bold, architectural presence to meadow plantings, wildflower gardens, and xeriscapes, thriving in poor, rocky soils where many other plants struggle.

The showy white flowers with bright yellow centers appear through summer, attracting bees and other pollinators. Its spiny leaves and stems add unusual texture to mixed borders and native plant collections. Grow it in full sun for best flowering, and allow spent blooms to self-sow for a naturalizing effect in wilder areas of the landscape. Handle with care due to the prickly foliage.
