10 Seeds Argemone glauca Hawaiian Prickly Poppy Perennial Flower

Argemone glauca, commonly known as the Hawaiian prickly poppy, is a striking perennial wildflower native to Hawaii. It produces large, poppy-like blooms with crinkled white petals and prominent yellow centers, accented by silvery blue-green foliage with prickly edges. Its bold, sculptural look makes it a standout accent in sunny garden beds and drought-tolerant landscapes.
This plant works well in xeriscapes, coastal gardens, and mixed perennial borders, where its long bloom season adds bright contrast. It grows best in well-drained soil and full sun, tolerating heat and dry conditions once established. Allow spent flowers to develop for continued interest, or remove them to encourage more blooms.
