Argemone glauca
(pua kala, beach poppy, Hawaiian poppy, Hawaiian prickly poppy, kala, naule)

Although they can be covered in prickles, the beautiful flowers are worth it to many gardeners because they are so easy to grow - they are also drought, wind, and heat tolerant. They can get weedy and grow wildly; dead head flowers if you want to minimize spread. One of the few native plants that can survive fires, pua kala has been seen to re-appear after soon after an area has been burned. Although it tends to be short-lived, it will re-establish easily when seeds germinate naturally. The flowers are iridescent white, and it is truely stunning in a dry, coastal landscape. The Hawaiian poppy is one of the few native plants found in cow pastures. Since cattle and possibly other ungulates (goats, sheep) will not eat pua kala, plants can be used as a beautiful, native border hedge to keep unwanted grazers from entering into fragile areas.
