Pricklypoppy plants tend to form large colonies. The whole plant is extremely spiny and stands up to three feet tall. The flower is white and measures approximately four inches in diameter. It can be found in disturbed areas, along fences, railroads, or in over-grazed pastures with sandy or gravelly soils. This plant’s flowering time is approximately between April and October. Although honeybees and other insects use its pollen, it yields very little nectar. The white-colored sap from this plant is poisonous. Because of the prickles, livestock will leave this plant untouched even during severe droughts.
