15 Seeds Prickly Poppy Argemone polyanthemos White Poppy Drought Tolerant Wildflower

Prickly Poppy is a striking wildflower native to the western United States, known for its large, papery white blooms and blue-green foliage. The flowers are accented by bright yellow centers and sit atop tall stems, creating a bold display in sunny gardens and meadow plantings. This species is valued for its drought tolerance and ability to thrive in poor, rocky soils where many other plants struggle.

Prickly Poppy works well in xeriscapes, native plant gardens, pollinator plantings, and wildflower meadows. The blooms appear through summer and attract bees and other beneficial insects. Plants have prickly leaves and stems, so they are best placed away from walkways and areas of frequent handling. Allow seed heads to mature for self-sowing or collect seeds for future plantings.
